Description

SUPPORT RECEVANT DES MOLECULES PRESENTANT UNE ACTIVITE ET PROCEDE POUR ASSURER LA PRESENCE DE TELLES MOLECULES SUR ON TEL SUPPORTCARRIER RECEIVING MOLECULES HAVING ACTIVITY AND METHOD FOR ENSURING THE PRESENCE OF SUCH MOLECULES ON SUCH CARRIER
La présente invention a trait, d'une part, à un dispositif de support recevant des molécules présentant une activité, soit à 1' encontre d'organismes ou de phénomènes indésirables, soit en faveur d'un phénomène désiré, d'autre part, à un procédé consistant à assurer la présence de ces molécules au niveau d'un tel support et, d'autre part encore, à une composition destinée à mettre en oeuvre ce procédé et/ou à être associée audit support.The present invention relates, on the one hand, to a support device receiving molecules having an activity, either against organisms or undesirable phenomena, or in favor of a desired phenomenon, on the other hand, to a process consisting in ensuring the presence of these molecules at the level of such a support and, on the other hand, to a composition intended to implement this process and / or to be associated with said support.
L'invention concerne le domaine du traitement des supports et trouvera son application lorsqu'il s'agit de réaliser des supports qui présentent des propriétés particulières, notamment dans le cadre de la protection de ce support ou d' un élément recevant un tel support, à l' encontre d'effets indésirables.The invention relates to the field of the treatment of supports and will find its application when it is a question of producing supports which have particular properties, in particular within the framework of the protection of this support or of an element receiving such a support, against undesirable effects.
L'on connaît, d'ores et déjà, un certain nombre de dispositifs de support présentant de telles propriétés et faisant appel, pour assurer la présence de molécules actives à leur niveau, à différents types de procédés. Un premier procédé consiste à assurer la fixation de molécules sur un support en réalisant une liaison covalente entre ce support et ces molécules. Tel est, par exemple, le cas, lorsqu'il s'agit de fixer des molécules colorantes sur un support, notamment cellulosique. Un tel procédé présente un certain nombre d'inconvénients consistant en ce que la réalisation d'une liaison covalente, d'une part, nécessite l'intervention de produits chimiques spécifiques ainsi qu'un apport substantiel d'énergie et, d'autre part et surtout, provoque une modification chimique irrémédiable du support ainsi que de la structure et de l'activité des molécules ce qui n' est pas admissible .We already know a certain number of support devices having such properties and calling, to ensure the presence of active molecules at their level, different types of processes. A first method consists in ensuring the attachment of molecules to a support by making a covalent bond between this support and these molecules. This is, for example, the case when it comes to fixing coloring molecules on a support, in particular cellulosic. Such a method has a certain number of drawbacks consisting in the fact that the production of a covalent bond, on the one hand, requires the intervention of specific chemicals as well as a substantial supply of energy and, on the other hand and above all, causes an irreversible chemical modification of the support as well as of the structure and the activity of the molecules which is not admissible.
Un autre procédé consiste à assurer la fixation de molécules sur un support en réalisant un collage de ces molécules à l'aide d'un liant. Un tel collage est, en fait, réalisé par polymérisation de ce liant à haute température ce qui présente un certain nombre d'inconvénients consistant, d'une part, en une rigidification du support et, d'autre part, en un noyage des molécules au sein du liant ce qui rend ces molécules totalement inactives.Another method consists in ensuring the attachment of molecules to a support by bonding these molecules using a binder. Such bonding is in fact carried out by polymerization of this binder at high temperature, which has a certain number of drawbacks consisting, on the one hand, in stiffening the support and, on the other hand, by flooding the molecules within the binder, which makes these molecules completely inactive.
Finalement, il est connu d'assurer la fixation de molécules sur un support en réalisant une liaison ionique entre ce support et ces molécules. Une tel procédé présente, là encore, un certain nombre d'inconvénients consistant en ce que, d'une part, la liaison ionique est particulièrement fragile et ne permet aucunement de fixer solidement une molécule sur un support et, d'autre part, la réalisation d'un tel type de liaison nécessite l'anionisation ou la cationisation du support au travers d'un traitement thermique provoquant, au moins en partie, une modification dudit support et/ou des molécules actives.Finally, it is known to fix molecules on a support by providing an ionic bond between this support and these molecules. Again, such a method has a certain number of drawbacks consisting in that, on the one hand, the ionic bond is particularly fragile and in no way makes it possible to firmly fix a molecule on a support and, on the other hand, the Achieving such a type of bond requires the anionization or cationization of the support through a heat treatment causing, at least in part, a modification of said support and / or of the active molecules.
La présente invention se veut à même de remédier aux inconvénients des dispositifs et des procédés de l'état de la technique.The present invention seeks to overcome the drawbacks of the devices and methods of the prior art.
A cet effet, l'invention concerne un procédé consistant à assurer la présence, au niveau d'un support, de molécules présentant une activité, notamment chimique, bio-chimique ou analogue, soit à 1' encontre d'organismes ou de phénomènes indésirables, soit en faveur d'un phénomène désiré, caractérisé par le fait que :To this end, the invention relates to a process consisting in ensuring the presence, at the level of a support, of molecules exhibiting an activity, in particular chemical, bio-chemical or similar, either against organisms or undesirable phenomena. , either in favor of a desired phenomenon, characterized by the fact that:
- l'on réalise une composition contenant, d'une part, des molécules actives et, d'autre part, une substance constituée par des molécules de type polymérisable et/ou réticulable susceptibles de former un réseau présentant au moins une zone amorphe ; - l'on assure la présence de cette composition au niveau de ce support ; l'on assure un piégeage d' une partie au moins desdites molécules actives au niveau d'au moins une zone amorphe définie par les molécules polymérisables et/ou réticulables contenues dans la composition présente au niveau dudit support, ceci tout en maintenant l'activité de ces molécules actives piégées.- A composition is produced containing, on the one hand, active molecules and, on the other hand, a substance constituted by molecules of the polymerizable and / or crosslinkable type capable of forming a network having at least one amorphous zone; - It ensures the presence of this composition at this support; at least part of said active molecules are trapped in at least one amorphous zone defined by the polymerizable and / or crosslinkable molecules contained in the composition present at said support, this while maintaining the activity of these trapped active molecules.
L'invention concerne, encore, un dispositif de support recevant des molécules présentant une activité, notamment chimique, biochimique ou analogue, soit à l' encontre d'organismes ou de phénomènes indésirables, soit en faveur d'un phénomène désiré, caractérisé par le fait qu'audit support sont associés des moyens agencés pour assurer un piégeage, au niveau de ce support, d'une partie au moins des molécules actives tout en maintenant l'activité des molécules actives piégées .The invention also relates to a support device receiving molecules having an activity, in particular chemical, biochemical or similar, either against organisms or undesirable phenomena, or in favor of a desired phenomenon, characterized by fact that audit support are associated means arranged to ensure trapping, at the level of this support, of at least part of the active molecules while maintaining the activity of the trapped active molecules.
Selon une autre caractéristique de l'invention, les moyens de piégeage sont constitués par une substance contenant des molécules de type polymérisable et/ou réticulable formant un réseau présentant au moins une zone amorphe au niveau de laquelle au moins une partie des molécules actives sont piégées.According to another characteristic of the invention, the trapping means consist of a substance containing molecules of the polymerizable and / or crosslinkable type forming a network having at least one amorphous zone at the level of which at least a portion of the active molecules are trapped .
Encore une autre caractéristique consiste en ce que les moyens de piégeage sont définis au niveau d'une superposition de plusieurs couches, d'une part, adsorbées à la surface dudit support, d'autre part, constituées, chacune, par une substance contenant des molécules polymérisables et/ou réticulables et, d'autre part encore, comportant, chacune, au moins une zone amorphe entre lesquelles et/ou à l'intérieur desquelles sont piégées lesdites molécules actives .Yet another characteristic consists in that the trapping means are defined at the level of a superposition of several layers, on the one hand, adsorbed on the surface of said support, on the other hand, each consisting of a substance containing polymerizable and / or crosslinkable molecules and, furthermore, each comprising at least one amorphous zone between which and / or inside which said active molecules are trapped.
L'invention concerne, encore, une composition destinée à mettre en œuvre le procédé mentionné ci-dessus et/ou destinée à être associée à un support en vue de l'obtention du dispositif de support décrit ci-dessus, cette composition étant caractérisée par le fait qu'elle contient, d'une part, des molécules actives et, d'autre part, une substance constituée par des molécules de type polymérisable et/ou réticulable susceptibles de former un réseau présentant au moins une zone amorphe. Les avantages de la présente invention consistent en ce que les molécules actives sont rendues solidaires du support par l'intermédiaire de moyens de piégeage, d'une part, assurant une fixation efficace de ces molécules sur le support et, d'autre part, n'affectant en rien l'activité de ces molécules actives. Un autre avantage concerne le fait que la mise en œuvre du procédé de réalisation d'un support recevant des molécules actives est aisée.The invention also relates to a composition intended to implement the method mentioned above and / or intended to be associated with a support with a view to obtaining the support device described above, this composition being characterized by the fact that it contains, on the one hand, active molecules and, on the other hand, a substance constituted by molecules of the polymerizable and / or crosslinkable type capable of forming a network having at least one amorphous zone. The advantages of the present invention consist in that the active molecules are made integral with the support by means of trapping means, on the one hand, ensuring an effective fixing of these molecules on the support and, on the other hand, n '' in no way affecting the activity of these active molecules. Another advantage relates to the fact that the implementation of the method for producing a support receiving active molecules is easy.
Encore un avantage de l'invention consiste en ce que ce procédé permet d'envisager, sans destruction ni inhibition, la fixation de nombreux types différents de molécules présentant une activité dans de nombreux domaines, ceci sur une grande quantité de supports de nature diverse et variée.Yet another advantage of the invention is that this process makes it possible to envisage, without destruction or inhibition, the fixation of many different types of molecules exhibiting activity in many fields, this on a large quantity of supports of diverse and varied nature.
Un avantage additionnel concerne le fait que les molécules actives peuvent être agencées sous forme de couches superposées susceptibles d'être retirées successivement (notamment par effet mécanique ou chimique comme, par exemple, par lavage, par friction ou autre du support) ce qui, d'une part, permet de maintenir l'activité du support et, d'autre part, autorise une activation successive de molécules identiques , voire différentes (par exemple pour une action différente) piégées au niveau dudit support.An additional advantage relates to the fact that the active molecules can be arranged in the form of superimposed layers which can be removed successively (in particular by mechanical or chemical effect such as, for example, by washing, by friction or other of the support) which, d on the one hand, makes it possible to maintain the activity of the support and, on the other hand, authorizes a successive activation of identical or even different molecules (for example for a different action) trapped at the level of said support.
L' invention est exposée plus en détail dans la description qui va suivre se rapportant à des modes de réalisation donnés à titre d'exemples et illustrés dans les figures des dessins ci-joints.The invention is set out in more detail in the description which follows, relating to embodiments given by way of examples and illustrated in the figures of the attached drawings.
La figure 1 est une vue schématisée correspondant à une étape du procédé selon l'invention consistant à assurer la présence d'une composition contenant des molécules actives et des molécules polymérisables et/ou réticulables au niveau du support, ceci selon un mode particulier de réalisation de cette invention.Figure 1 is a schematic view corresponding to a step of the method according to the invention consisting in ensuring the presence of a composition containing active molecules and polymerizable and / or crosslinkable molecules at the support, this according to a particular embodiment of this invention.
La figure 2 est une vue schématisée correspondant à un dispositif de support selon l'invention au niveau duquel a été assurée la présence d'une composition contenant des molécules actives et des molécules polymérisables et/ou réticulables.Figure 2 is a schematic view corresponding to a support device according to the invention at which the presence has been ensured of a composition containing active molecules and polymerizable and / or crosslinkable molecules.
La figure 3 est une vue schématisée d'un dispositif de support selon l'invention présentant des zones amorphes au niveau desquelles sont piégées des molécules actives .FIG. 3 is a diagrammatic view of a support device according to the invention having amorphous zones at the level of which active molecules are trapped.
La présente invention concerne le domaine du traitement des supports et trouvera son application lorsqu'il s'agit de réaliser des supports qui présentent des propriétés particulières, par exemple lorsqu'il s'agit d'assurer la protection de ce support ou d'un élément recevant un tel support, ceci à l' encontre d'effets indésirables .The present invention relates to the field of treatment of supports and will find its application when it is a question of producing supports which have particular properties, for example when it is a question of ensuring the protection of this support or of a element receiving such support, this against undesirable effects.
Afin de conférer de telles propriétés à un support 1, il convient d'assurer la présence, au niveau de ce support 1, de molécules 2, 2' présentant une activité, notamment chimique, bio- chimique ou analogue. Une telle activité peut, selon un premier type de support 1, s'exercer à l' encontre d'organismes (micro-organismes, animaux, végétaux...) ou de phénomènes (rayonnement...) indésirables, ou encore et selon un autre type de support 1, s'exercer en faveur de phénomènes désirés (coloration...) .In order to confer such properties on a support 1, it is necessary to ensure the presence, at the level of this support 1, of molecules 2, 2 ′ having an activity, in particular chemical, biochemical or similar. According to a first type of support 1, such an activity can be exercised against organisms (micro-organisms, animals, plants, etc.) or undesirable phenomena (radiation, etc.), or even and according to another type of support 1, exercising in favor of desired phenomena (coloring, etc.).
L'invention concerne, alors, un dispositif de support 1 auquel sont associés des moyens 3 agencés pour assurer un piégeage, au niveau de ce support 1, d'une partie 2 au moins desdites molécules actives 2, 2' présentes au niveau de ce support 1. Ces moyens de piégeage 3 sont, par ailleurs et malgré leur fonction de piégeage, conçus aptes à maintenir l'activité desdites molécules actives 2 selon le cas, à l' encontre des organismes/phénomènes indésirables ou en faveur des phénomènes désirés .The invention therefore relates to a support device 1 to which are associated means 3 arranged to ensure trapping, at the level of this support 1, of at least part 2 of said active molecules 2, 2 ′ present at this level. support 1. These trapping means 3 are, moreover and despite their trapping function, designed capable of maintaining the activity of said active molecules 2, as the case may be, against undesirable organisms / phenomena or in favor of the desired phenomena.
Selon une autre caractéristique de l'invention et tel que visible figure 3, le dispositif de support 1 reçoit, au niveau de sa surface 4 et/ou dans son volume 5 , une substance 6 contenant des molécules de type polymérisable et/ou réticulable susceptibles de former un réseau présentant au moins une zone amorphe 7 ainsi qu'au moins une zone cristalline 8.According to another characteristic of the invention and as visible in FIG. 3, the support device 1 receives, at its surface 4 and / or in its volume 5, a substance 6 containing molecules of the polymerizable and / or crosslinkable type capable of to form a network having at least one amorphous zone 7 as well as at least one crystalline zone 8.
A ce propos, on observera que c'est, plus particulièrement, au niveau d'une telle zone cristalline 8 qu'est réalisée une fixation, sur ledit support 1, de ladite substance 6, cette dernière 6 étant, en fait, conçue apte à rendre lesdites molécules actives 2, 2' solidaires de ce support 1.In this regard, it will be observed that it is, more particularly, at the level of such a crystalline zone 8 that a fixing is carried out, on said support 1, of said substance 6, the latter 6 being, in fact, designed capable in making said active molecules 2, 2 ′ integral with this support 1.
En fait, certaines de ces molécules actives 2' peuvent être emprisonnées , selon le cas , au sein d' une zone cristalline 8 ou entre une telle zone cristalline 8 et ledit support 1 (figure 3) . De telles molécules actives 2' , du fait leur emprisonnement, sont inhibées et perdent leur activité à l' encontre des organismes/phénomènes indésirables ou en faveur des phénomènes désirés Cependant et tel que visible sur la figure 3, d'autre molécules actives 2 se retrouvent au niveau d' au moins une zone amorphe 7 constituant lesdits moyens de piégeage 3 de ces molécules 2 assurant la solidarisation de ces dernières 2 dudit support 1 tout en maintenant leur activité, selon le cas, à l' encontre des organismes/phénomènes indésirables ou en faveur des phénomènes désirés . Il convient d'observer que la substance 4 contient des molécules de type polymérisable et/ou réticulable qui , par polymérisation et/ou réticulation incomplète, sont susceptibles de constituer au moins une zone amorphe 7. Aussi , la zone amorphe 7 , au niveau de laquelle sont piégées lesdites molécules actives 2 , est constituée par une polymérisation et/ou une réticulation incomplète des molécules polymérisables et/ou réticulables entrant dans la composition de la substance 6 définissant lesdits moyens de piégeage 3. A ce propos, on observera que la réalisation d'une telle zone amorphe 7 peut être assurée de différentes manières comme, par exemple, en soumettant ladite substance 6 à un rayonnement (notamment UV ou autre) pendant une durée déterminée.In fact, some of these active molecules 2 ′ can be trapped, as the case may be, within a crystalline zone 8 or between such a crystalline zone 8 and said support 1 (FIG. 3). Due to their imprisonment, such active molecules 2 ′ are inhibited and lose their activity against undesirable organisms / phenomena or in favor of the desired phenomena. However, as shown in FIG. 3, other active molecules 2 are find at least one amorphous zone 7 constituting said trapping means 3 of these molecules 2 ensuring the joining of the latter 2 of said support 1 while maintaining their activity, as the case may be, against undesirable organisms / phenomena or in favor of the desired phenomena. It should be observed that substance 4 contains molecules of polymerizable and / or crosslinkable type which, by incomplete polymerization and / or crosslinking, are capable of constituting at least one amorphous zone 7. Also, the amorphous zone 7, at the level of which are trapped said active molecules 2, is constituted by a polymerization and / or incomplete crosslinking of the polymerizable and / or crosslinkable molecules entering into the composition of substance 6 defining said trapping means 3. In this regard, it will be observed that the realization such an amorphous zone 7 can be ensured in different ways such as, for example, by subjecting said substance 6 to radiation (in particular UV or other) for a determined period.
Cependant et selon un mode de réalisation préféré de l'invention, une telle zone amorphe 7, au niveau de laquelle sont piégées lesdites molécules actives 2, est constituée par une portion asséchée de la substance 6 contenant les molécules polymérisables et/ou réticulables.However and according to a preferred embodiment of the invention, such an amorphous zone 7, at the level of which said active molecules 2 are trapped, is constituted by a dried portion of the substance 6 containing the polymerizable and / or crosslinkable molecules.
C'est, plus particulièrement, au travers d'un tel séchage qu'il est assuré une polymérisation et/ou une réticulation incomplète des molécules polymérisables et/ou réticulables entrant dans la composition de cette substance 6.It is, more particularly, through such drying that an incomplete polymerization and / or crosslinking of the polymerizable and / or crosslinkable molecules used in the composition of this substance 6 is ensured.
Selon une autre caractéristique de l'invention, les moyens de piégeage 3 sont définis au niveau d'au moins une couche, d'une part, adsorbée à la surface 4 dudit support 1 et, d'autre part, constituée par une substance 6 contenant des molécules polymérisables et/ou réticulables. Une telle couche comporte au moins une zone amorphe 7 à l'arrière de laquelle et/ou à l'intérieur de laquelle sont piégées lesdites molécules actives 2. Selon un premier mode de réalisation, lesdites molécules actives 2 peuvent être piégées à l'arrière d'une telle zone amorphe 7. Dans un pareil cas , les molécules polymérisables et/ou réticulables sont susceptibles de former un réseau présentant des ouvertures dont la section est inférieure à celle d'une molécule active 2 de sorte que cette dernière 2 est piégées par le réseau, à l'arrière de ce dernier, tout en restant active vis à vis du milieu extérieur.According to another characteristic of the invention, the trapping means 3 are defined at the level of at least one layer, on the one hand, adsorbed on the surface 4 of said support 1 and, on the other hand, constituted by a substance 6 containing polymerizable and / or crosslinkable molecules. Such a layer comprises at least one amorphous zone 7 behind which and / or inside which said active molecules are trapped 2. According to a first embodiment, said active molecules 2 can be trapped at the rear of such an amorphous zone 7. In such a case, the polymerizable and / or crosslinkable molecules are capable of forming a network having openings whose cross section is smaller than that of an active molecule 2 so that the latter 2 is trapped through the network, to the rear of the latter, while remaining active with respect to the external environment.
Selon un autre mode de réalisation, lesdites molécules actives 2 peuvent être piégées à l'intérieur d'une telle zone amorphe 7. Dans un pareil cas, les molécules polymérisables et/ou réticulables sont susceptibles de former un réseau constitué par des canaux ou analogue à l'intérieur desquels sont piégées lesdites molécules actives 2 tout en restant actives vis à vis du milieu extérieur.According to another embodiment, said active molecules 2 can be trapped inside such an amorphous zone 7. In such a case, the polymerizable and / or crosslinkable molecules are capable of forming a network constituted by channels or the like. inside which said active molecules 2 are trapped while remaining active with respect to the external environment.
Cependant et selon un mode de réalisation préféré de 1' invention, lesdits moyens de piégeage 3 sont définis au niveau d'une superposition de plusieurs couches, d'une part, adsorbées à la surface 4 dudit support 1, d'autre part, constituées, chacune, par une substance 6 contenant des molécules polymérisables et/ou réticulables et, d'autre part encore, comportant, chacune, au moins une zone amorphe 7 entre lesquelles et/ou à l'intérieur desquelles sont piégées lesdites molécules actives 2. De telles couches adoptent, de préférence, une structure de type susmentionné (réseau à ouvertures ou canaux) .However and according to a preferred embodiment of the invention, said trapping means 3 are defined at the level of a superposition of several layers, on the one hand, adsorbed on the surface 4 of said support 1, on the other hand, constituted , each by a substance 6 containing polymerizable and / or crosslinkable molecules and, on the other hand, also, each comprising at least one amorphous zone 7 between which and / or inside which said active molecules 2 are trapped. Such layers preferably adopt a structure of the aforementioned type (network with openings or channels).
A ce propos , on observera qu' un mode préféré de réalisation de l'invention consiste en ce que les zones amorphes 7 de plusieurs couches superposées sont elles-même superposées.In this regard, it will be observed that a preferred embodiment of the invention consists in that the amorphous zones 7 of several superimposed layers are themselves superimposed.
On remarquera qu' une zone amorphe 7 présente une plus grande fragilité qu'une zone cristalline 8. Aussi et au travers d'un traitement approprié, il est possible de procéder au retrait d'une partie d'une couche de substance 6 correspondant à une zone amorphe 7 de cette couche. Un tel mode de réalisation permet, avantageusement, de retirer du support 1 des molécules actives 2 piégées par une couche supérieure et ayant perdu de leur activité pour amener à proximité de la surface les molécules actives 2 piégées par une couche inférieure n' ayant eu que peu ou pas d' activité .It will be noted that an amorphous zone 7 has greater brittleness than a crystalline zone 8. Also and through an appropriate treatment, it is possible to remove part of a layer of substance 6 corresponding to an amorphous zone 7 of this layer. Such an embodiment advantageously makes it possible to remove from the support 1 active molecules 2 trapped by an upper layer and having lost their activity in order to bring the active molecules 2 trapped by a lower layer close to the surface having only had little or no activity.
Il convient d'observer qu'un traitement approprié peut consister en un traitement de type mécanique et/ou chimique. A titre d'exemple, un tel traitement peut consister en une friction, en une abrasion, en un lavage dudit support 1, ceci dans des conditions (notamment de température) particulières . Selon une autre caractéristique de l'invention, la ou les zones amorphes 7 et/ou les molécules actives 2 (piégées par une telle zone amorphe 7) peuvent être susceptibles de subir une déformation permettant à une telle molécule active 2 de traverser ou de s'extraire d'une couche de substance 6 pour être libérée dans le milieu extérieur. A ce propos , on observa que la déformation d' une molécule active 2 peut, par exemple, être occasionnée par un insecte ou analogue (par exemple un moustique) venant au contact d'une telle molécule 2. La déformation d' une telle molécule 2 et/ou d' ne zone amorphe 7 peut, encore, résulter d'un contact volontaire avec un élément extérieur au support 1, notamment un contact avec la peau (par exemple pour des molécules actives de type médicamenteuses à diffusion transcutanée) ou d'un contact par friction, tamponnage ou analogue, ceci dans le cadre d'un traitement visant à assurer, volontairement, une libération de telles molécules actives 2.It should be noted that an appropriate treatment may consist of a mechanical and / or chemical treatment. By way of example, such a treatment can consist of friction, abrasion, washing of said support 1, this under particular conditions (in particular of temperature). According to another characteristic of the invention, the amorphous zone or zones 7 and / or the active molecules 2 (trapped by such an amorphous zone 7) may be liable to undergo a deformation allowing such an active molecule 2 to pass through or s 'extract from a layer of substance 6 to be released into the outside environment. In this regard, it was observed that the deformation of an active molecule 2 can, for example, be caused by an insect or the like (for example a mosquito) coming into contact with such a molecule 2. The deformation of such a molecule 2 and / or an amorphous zone 7 can also result from voluntary contact with an element external to the support 1, in particular contact with the skin (for example for active molecules of the drug type with transcutaneous diffusion) or d 'a contact by friction, buffering or the like, this in the context of a treatment aimed at ensuring, voluntarily, a release of such active molecules 2.
En ce qui concerne les molécules 2, 2' présentant une activité, selon le cas, à l' encontre des organismes/phénomènes indésirables ou en faveur des phénomènes désirés, celles-ci 2, 2' peuvent se présenter sous une forme émulsionnable, dispersible ou soluble dans un solvant, notamment de l'eau.With regard to the molecules 2, 2 ′ exhibiting an activity, as the case may be, against undesirable organisms / phenomena or in favor of the desired phenomena, these 2, 2 ′ may be in an emulsifiable, dispersible form or soluble in a solvent, in particular water.
Selon une première catégorie, de telles molécules actives 2 présentent une activité à l' encontre des insectes (rampants, volants ou autre) et peuvent être de type insecticide, insectifuge ou analogue. A titre d'exemple non limitatif, il est possible d'employer des molécules insectifuges telles que la permethrine, la deltamethrine ou analogue. Il est, encore, possible d'employer des molécules insecticides et insectifuges comme, par exemple, la bifenthrine ou l'ethophen prox.According to a first category, such active molecules 2 exhibit activity against insects (crawling, flying or otherwise) and can be of the insecticide, insect repellant or similar type. By way of nonlimiting example, it is possible to use insect repellent molecules such as permethrin, deltamethrine or the like. It is, again, possible to use insecticidal and repellant molecules such as, for example, bifenthrin or ethophen prox.
Une autre catégorie de molécules actives 2 consiste en celles présentant une activité à l' encontre des bactéries, des microbes (molécule du type isothiazolinone ou analogue) , des acariens (molécule du type triclosan ou analogue) ou analogue.Another category of active molecules 2 consists of those exhibiting activity against bacteria, microbes (molecule of the isothiazolinone type or the like), mites (molecule of the triclosan type or the like) or the like.
Encore une autre catégorie concerne des molécules actives 2 présentant une activité à l' encontre des végétaux, notamment les mousses . Il est une catégorie de molécules actives 2 présentent une activité dans le traitement prophylaxique ou curatif d'une maladie.Yet another category relates to active molecules 2 exhibiting activity against plants, in particular mosses. There is a category of active molecules 2 which have activity in the prophylaxis or curative treatment of a disease.
Il est, encore, des molécules actives 2 présentent une activité à l' encontre de la fixation de produits tachants sur le support 1 qui les reçoit.It is, still, active molecules 2 have an activity against the fixing of staining products on the support 1 which receives them.
Une autre catégorie concerne celle des molécules actives 2 présentent une activité à l' encontre des rayonnements, notamment Ultra-violets .Another category concerns that of the active molecules 2 which exhibit activity against radiation, in particular Ultra-violet.
Finalement, il peut encore être envisagé des molécules actives 2 présentent une activité de coloration du support 1.Finally, it is also possible to envisage active molecules 2 exhibiting a coloring activity of the support 1.
En ce qui concerne le support 1 destiné à recevoir des molécules actives 2, 2', celui-ci 1 peut être de différents types.As regards the support 1 intended to receive active molecules 2, 2 ′, the latter 1 can be of different types.
Aussi et selon un premier mode de réalisation, ce support 1 peut être constitué, au moins en partie, par un matériau textile. Un tel matériau peut être du type tricoté, tissé, non tissé ou autre et être constitué par des fibres et/ou des filaments naturels, artificiels ou synthétique comme par exemple, du polyester, du viscose, du coton, de la laine, du polyamide, de la soie, ou encore un mélange de différentes fibres et/ou filaments . Un mode particulier de réalisation consiste en ce que le support est un élément vestimentaire (une chemise, un pull, un pantalon, une veste ou autre) .Also and according to a first embodiment, this support 1 can be constituted, at least in part, by a textile material. Such a material can be of the knitted, woven, non-woven or other type and consist of natural, artificial or synthetic fibers and / or filaments such as, for example, polyester, viscose, cotton, wool, polyamide. , silk, or a mixture of different fibers and / or filaments. A particular embodiment consists in that the support is a clothing element (a shirt, a sweater, pants, a jacket or the like).
A ce propos, on observera qu'une application de l'invention peut consister à assurer la présence, au niveau d'un tel élément vestimentaire, de molécules présentant une activité à l' encontre des insectes (par exemple les moustiques), des bactéries, des microbes, des acariens (par exemple les tiques) , des produits tachants ou encore des rayonnements .In this regard, it will be observed that an application of the invention may consist in ensuring the presence, at the level of such a clothing element, of molecules exhibiting an activity against insects (for example mosquitoes), bacteria , microbes, mites (for example ticks), staining products or even radiation.
Un tel élément vestimentaire peut aussi recevoir des molécules conçues aptes à colorer le support 1 ou présentant une activité dans le traitement prophylaxique ou curatif d'une maladie à laquelle peut être sujet le porteur de ce vêtement.Such a clothing element can also receive molecules designed capable of coloring the support 1 or having an activity in the prophylaxis or curative treatment of a disease to which the wearer of this garment may be subject.
Selon une autre application, des molécules 2 présentant une activité à l' encontre des insectes (par exemple les moustiques) , des bactéries, des microbes, des acariens (par exemple les tiques) , des produits tachants ou des rayonnements peuvent, encore, être associées à un support 1 défini par un tissu sous forme d'un voilage (plus particulièrement une moustiquaire, des rideaux, des doubles rideaux ou autre) .According to another application, molecules 2 exhibiting activity against insects (for example mosquitoes), bacteria, microbes, mites (for example ticks), staining products or radiation can also be associated with a support 1 defined by a fabric in the form of a curtain (more particularly a mosquito net, curtains, double curtains or the like).
Des molécules 2 présentant des telles activités ainsi que des molécules présentant une activité, soit à l' encontre des végétaux (notamment les mousses ou autre) , soit en faveur de la coloration, peuvent être associées à un support 1 constitué par un élément constitutif d'un bâtiment, comme, par exemple, un mur, un dispositif de fermeture (notamment une porte, une fenêtre, un volet ou analogue) , un store, un toit, un balcon, une terrasse, des pavés ou, encore, un revêtement rapporté sur un tel élément constitutif.Molecules 2 exhibiting such activities as well as molecules exhibiting activity, either against plants (in particular mosses or the like), or in favor of coloring, can be combined with a support 1 constituted by a constituent element of '' a building, such as, for example, a wall, a closing device (in particular a door, a window, a shutter or the like), a blind, a roof, a balcony, a terrace, paving stones or, again, a covering reported on such a constituent element.
Les applications évoquées ci-dessus ne sont, en fait, aucunement limitatives et, selon un avantage substantiel de l'invention, il peut être envisagé d'associer, à un support 1 quelconque, réalisé en un matériau quelconque (bois, béton, tissu, métal, cuir, céramique...) , toute sorte de molécules actives 2 ou toute sorte de mélange de molécules actives 2 (d' activité similaires, identiques, différents, complémentaires) selon le ou les types d'activités que l'on souhaite conférer à ce support 1. En ce qui concerne les molécules entrant dans la composition de la substance 4 , celles-ci peuvent être de type polymérisable et/ou réticulable .The applications mentioned above are in fact in no way limiting and, according to a substantial advantage of the invention, it can be envisaged to associate, with any support 1, made of any material (wood, concrete, fabric , metal, leather, ceramic ...), any kind of active molecules 2 or any kind of mixture of active molecules 2 (of similar, identical, different, complementary activity) according to the type or types of activities that one wishes to confer on this support 1. With regard to the molecules entering into the composition of substance 4, these can be of the polymerizable and / or crosslinkable type.
A ce propos et à titre d'exemple non limitatif, il peut être cité comme molécule polymérisable, un dérivé acrylique, du styrène butadiène, du polyuréthane, de l'acétate de vinyle, de l'uréthane ou autre.In this regard and by way of nonlimiting example, it may be cited as polymerizable molecule, an acrylic derivative, styrene butadiene, polyurethane, vinyl acetate, urethane or the like.
Quant aux molécules réticulables, celles-ci peuvent, de manière non limitative, être constituées par des résines de type mélamine formol, méthylol-urée, diméthyloldihydroxyethylène urée, urée formol ou autre.As for the crosslinkable molecules, these may, without limitation, be constituted by resins of the melamine formaldehyde, methylol-urea, dimethyloldihydroxyethylene urea, formalin urea or other type.
Il est évident que la substance 4 peut contenir l'une quelconque de ces molécules , voire encore un mélange de plusieurs de ces molécules .It is obvious that substance 4 can contain any of these molecules, or even a mixture of several of these molecules.
A ce propos, il convient d'observer que cette substance 4 peut, encore, contenir au moins un catalyseur constitué, par exemple, par un catalyseur de type acide tel que l' acide acétique, l' acide formique ou autre ou encore un mélange de tels acides .In this regard, it should be noted that this substance 4 may also contain at least one catalyst consisting, for example, of an acid type catalyst such as acetic acid, formic acid or the like or a mixture of such acids.
La présente invention concerne, encore, un procédé consistant à assurer la présence, au niveau d'un support 1, de molécules 2, 2' présentant une activité, notamment chimique, bio-chimique ou analogue, du type évoqué ci-dessus, ceci soit à l' encontre d'organismes ou de phénomènes indésirables, soit en faveur d'un phénomène désiré.The present invention also relates to a method consisting in ensuring the presence, at the level of a support 1, of molecules 2, 2 ′ exhibiting an activity, in particular chemical, bio-chemical or similar, of the type mentioned above, this either against organisms or undesirable phenomena, or in favor of a desired phenomenon.
La mise en œuvre de ce procédé permet, notamment, de réaliser le dispositif de support 1 tel que décrit ci-dessus.The implementation of this method makes it possible, in particular, to produce the support device 1 as described above.
En fait, ce procédé consiste en ce que :In fact, this process consists in that:
- l'on réalise une composition 9 contenant, d'une part, des molécules actives 2, 2' et, d'autre part, une substance 4 constituée par des molécules de type polymérisable et/ou réticulable susceptibles de former un réseau présentant au moins une zone amorphe 7 ;- A composition 9 is produced containing, on the one hand, active molecules 2, 2 ′ and, on the other hand, a substance 4 consisting of molecules of the polymerizable and / or crosslinkable type capable of forming a network having at minus an amorphous zone 7;
- l'on assure la présence de cette composition 9 au niveau dudit support 1 ;- It ensures the presence of this composition 9 at said support 1;
- l'on assure un piégeage d'une partie au moins desdites molécules actives 2 au niveau d'au moins une zone amorphe 7 définie par les molécules polymérisables et/ou réticulables contenues dans la composition 9 présente au niveau dudit support 1, ceci tout en maintenant l'activité de ces molécules 2.- It ensures a trapping of at least part of said active molecules 2 at at least one amorphous zone 7 defined by the polymerizable and / or crosslinkable molecules contained in the composition 9 present at said support 1, this all by maintaining the activity of these molecules 2.
A ce propos, on observera que la composition 9, contenant les molécules actives 2, 2' ainsi que les molécules polymérisables et/ou réticulables, est, usuellement, réalisée en présence d'un solvant qui peut être, par exemple, l'eau.In this regard, it will be observed that composition 9, containing the active molecules 2, 2 ′ as well as the polymerizable and / or crosslinkable molecules, is usually produced in the presence of a solvent which can be, for example, water .
Selon un premier mode de réalisation, les molécules polymérisables et/ou réticulables peuvent nécessiter la présence d'un catalyseur pour polymériser et/ou réticuler comme il est, par exemple, le cas pour des molécules polymérisables et/ou réticulables à haute température.According to a first embodiment, the polymerizable and / or crosslinkable molecules may require the presence of a catalyst to polymerize and / or crosslink as it is, for example, the case for molecules which can be polymerized and / or crosslinkable at high temperature.
Aussi et lorsque l'on réalise une composition 9 contenant une substance 4 constituée par des molécules polymérisables et/ou réticulables à haute température, l'on rajoute un catalyseur à cette composition 9. Cependant et selon un autre mode de réalisation, la compositionAlso and when a composition 9 is produced containing a substance 4 consisting of polymerizable and / or crosslinkable molecules at high temperature, a catalyst is added to this composition 9. However and according to another embodiment, the composition
9 peut contenir une substance 4 constituée par des molécules susceptibles de polymériser et/ou de réticuler en l'absence de catalyseur, plus particulièrement, par auto-polymérisation ou auto- réticulation.9 may contain a substance 4 consisting of molecules capable of polymerizing and / or of crosslinking in the absence of catalyst, more particularly, by self-polymerization or self-crosslinking.
Selon une autre caractéristique de l'invention, l'on assure la présence de cette composition 9 au niveau dudit support 1.According to another characteristic of the invention, the presence of this composition 9 is ensured at the level of said support 1.
Aussi et selon un premier mode de réalisation représenté figure 1, ce support 1 peut être immergé dans un bain 10 contenant une telle composition 9, un tel bain 10 étant, par exemple, réalisé dans une cuve, notamment de machine à laver. Un tel mode de réalisation peut être envisagé dans le cas d'un support 1 adoptant la forme d'un tissu ou analogue.Also and according to a first embodiment represented in FIG. 1, this support 1 can be immersed in a bath 10 containing such a composition 9, such a bath 10 being, for example, produced in a tank, in particular of a washing machine. Such an embodiment can be envisaged in the case of a support 1 adopting the form of a fabric or the like.
Selon un autre mode de réalisation, il est procédé à une pulvérisation de cette composition 9 sur ledit support 1, ceci par l'intermédiaire d'un pulvérisateur adoptant, par exemple, la forme d'au moins une buse. Un tel mode de réalisation peut, par exemple, être envisagé dans le cadre d' un support 1 adoptant la forme d' un toit, d'un store ou analogue. Encore un autre mode de réalisation consiste en ce que l'on applique une telle composition 9 sur ledit support 1 , ceci par l'intermédiaire d'un pinceau ou d'un rouleau. Il peut en être ainsi lorsque ce support 1 adopte la forme d'une terrasse, d'un mur ou autre. Dans un pareil cas il convient, usuellement, d'assurer un épaississement de la composition 9 en rajoutant à cette dernière 9 un épaississant, selon le cas, de type synthétique (comme par exemple un acrylate ou autre) ou naturel (comme par exemple un alginate de sodium ou autre) .According to another embodiment, this composition 9 is sprayed on said support 1, this by means of a sprayer adopting, for example, the shape of at least one nozzle. Such an embodiment can, for example, be envisaged in the context of a support 1 adopting the form of a roof, a blind or the like. Yet another embodiment consists in applying such a composition 9 to said support 1, this by means of a brush or a roller. This can be so when this support 1 takes the form of a terrace, a wall or the like. In such a case, it is usually necessary to ensure a thickening of the composition 9 by adding to the latter 9 a thickener, as the case may be, of synthetic type (such as for example an acrylate or other) or natural (such as for example a sodium alginate or other).
Il est évident que, selon un premier mode de réalisation de l'invention, il est possible d'assurer la présence de ladite composition 9 au niveau du support 1 en procédant à une seule immersion, à une seule pulvérisation ou à une seule application. Cependant et selon un mode de réalisation préféré de l'invention, il est préférable de renouveler une telle immersion/pulvérisation/application. Un tel mode de réalisation permet, notamment de déposer une pluralité de couches superposées de la composition 9 ou de la substance 6 sur le support 1.It is obvious that, according to a first embodiment of the invention, it is possible to ensure the presence of said composition 9 at the level of the support 1 by carrying out a single immersion, a single spraying or a single application. However and according to a preferred embodiment of the invention, it is preferable to repeat such immersion / spraying / application. Such an embodiment allows, in particular to deposit a plurality of superimposed layers of composition 9 or substance 6 on the support 1.
Tel qu'évoqué ci-dessus, l'on assure le piégeage des molécules actives 2 dans au moins une zone amorphe 7 de la substance 6 que contient ladite composition 9. En fait, un tel piégeage est assuré en procédant à une polymérisation et/ou une réticulation incomplète des molécules polymérisables et/ou réticulables contenues dans cette composition 9.As mentioned above, the active molecules 2 are trapped in at least one amorphous zone 7 of the substance 6 contained in said composition 9. In fact, such trapping is ensured by carrying out a polymerization and / or an incomplete crosslinking of the polymerizable and / or crosslinkable molecules contained in this composition 9.
A ce propos, on observera que ce piégeage des molécules actives 2 dans une zone amorphe 7 peut être réalisé en procédant au séchage de ladite composition 9 sous une température notablement inférieure à la température de polymérisation et/ou de réticulation des molécules polymérisables et/ou réticulables contenues dans la composition. En fait, au travers d'un tel séchage, il est assuré une polymérisation et/ou une réticulation incomplète de ces molécules laissant place à un réseau non structuré présentant des zones amorphes 7 où des molécules actives 2 sont piégées.In this regard, it will be observed that this trapping of the active molecules 2 in an amorphous zone 7 can be carried out by drying said composition 9 at a temperature significantly below the polymerization and / or crosslinking temperature of the polymerizable molecules and / or crosslinkable contained in the composition. In fact, through such drying, polymerization and / or incomplete crosslinking of these molecules is ensured, leaving room for an unstructured network having amorphous zones 7 where active molecules 2 are trapped.
C'est, également, au travers d'une telle polymérisation/réticulation incomplète et/ou du séchage desdites molécules que l'on assure une fixation de la substance 6 (et par conséquent des molécule actives 2, 2') sur ledit support 1.It is also through such incomplete polymerization / crosslinking and / or drying of said molecules that the substance 6 (and consequently the active molecules 2, 2 ′) is fixed on said support 1 .
Selon une autre caractéristique de l'invention, le séchage est assuré à une température basse en comparaison avec la température de polymérisation et/ou de réticulation des molécules contenues dans la substance 6.According to another characteristic of the invention, drying is ensured at a low temperature in comparison with the polymerization and / or crosslinking temperature of the molecules contained in substance 6.
En fait, un tel séchage de la composition 9 s'opère à une température inférieure à 70°C, de préférence inférieure à 50°C, ceci, de préférence, à l'air libre, dans un four ou analogue.In fact, such drying of the composition 9 takes place at a temperature below 70 ° C, preferably below 50 ° C, this, preferably, in the open air, in an oven or the like.
A ce propos, il convient d'observer que, dans le cas d'une immersion du support 1 dans un bain 10, il est possible, avant de procéder au séchage, d'assurer un essorage dudit support 1.In this regard, it should be noted that, in the case of immersion of the support 1 in a bath 10, it is possible, before proceeding to drying, to ensure a wringing of said support 1.
La présente invention concerne, encore, une composition chimique 9 destinée à mettre en œuvre le procédé décrit ci-dessus et/ou destinée à être associée à un support 1 en vue de l'obtention du dispositif de support 1 susmentionné. Une telle composition 9 contient, alors, d'une part, des molécules actives 2, 2' et, d'autre part, une substance 4 constituée par des molécules de ype polymérisable et/ou réticulable susceptibles de former un réseau présentant au moins une zone amorphe 7.The present invention also relates to a chemical composition 9 intended to implement the method described above and / or intended to be associated with a support 1 with a view to obtaining the above-mentioned support device 1. Such a composition 9 then contains, on the one hand, active molecules 2, 2 ′ and, on the other hand, a substance 4 constituted by molecules of polymerizable and / or crosslinkable ype capable of forming a network having at least one amorphous zone 7.
Il est, encore, donné un exemple d'une telle composition 9 :It is, again, given an example of such a composition 9:
- 50 à 100 grammes par litre d'une solution aqueuse d'un polymère de dérivé acrylique ;- 50 to 100 grams per liter of an aqueous solution of a polymer of acrylic derivative;
- 10 grammes par litre d'une solution aqueuse de résine mélamine formol ;- 10 grams per liter of an aqueous solution of melamine formaldehyde;
- 40 grammes par litre d'une solution de permethrine en émulsion à 50% ;- 40 grams per liter of a solution of permethrin in emulsion at 50%;
- éventuellement un catalyseur sous la forme d'une solution à 10 grammes par litre d'acide acétique à 80%. - optionally a catalyst in the form of a solution of 10 grams per liter of 80% acetic acid.
