Description
La présente invention concerne une nouvelle couche ultra-mince hydrophobe et oléophobe formée par auto-assemblage sur une surface de substrat solide de composés à pied catéchol, un procédé pour préparer cette couche ultra-mince et l'utilisation de celle-ci comme épilame.The present invention relates to a new ultra-thin hydrophobic and oleophobic layer formed by self-assembly on a solid substrate surface of catechol foot compounds, a process for preparing this ultra-thin layer and the use thereof as an epilame.
Le bon fonctionnement d'un mouvement horloger dépend entre autre de sa lubrification. La durabilité du lubrifiant dépend notamment de son maintien dans la zone de fonctionnement : tout horloger a cependant constaté qu'une goutte de lubrifiant s'étale rapidement sur une pièce propre. Le dépôt d'une couche d'épilame, généralement sous la forme d'une couche moléculaire invisible hydrophobe et oléophobe, permet d'éviter l'étalement du lubrifiant et de ses composants.The proper functioning of a watch movement depends, among other things, on its lubrication. The durability of the lubricant depends in particular on its maintenance in the operating zone: every watchmaker, however, has noticed that a drop of lubricant spreads rapidly over a clean part. The deposition of an epilame layer, generally in the form of a hydrophobic and oleophobic invisible molecular layer, avoids the spreading of the lubricant and its components.
L'étalement d'un liquide dépend des forces d'interaction entre le liquide, la surface et l'air environnant (Cf.
L'énergie de surface dépend de plusieurs facteurs (
- la composition chimique et la structure cristallographique du solide, et en particulier de sa surface,
- les caractéristiques géométriques de la surface et sa rugosité (et donc les défauts et/ou l'état de polissage),
- la présence de molécules adsorbées physiquement ou liées chimiquement à la surface, qui peuvent aisément masquer le solide et modifier considérablement son énergie de surface.
- the chemical composition and the crystallographic structure of the solid, and in particular of its surface,
- the geometric characteristics of the surface and its roughness (and therefore the defects and / or the polishing state),
- the presence of molecules physically adsorbed or chemically bonded to the surface, which can easily hide the solid and significantly alter its surface energy.
L'énergie de surface est souvent déterminée par la dernière couche atomique ou moléculaire. La nature chimique du solide a peu d'importance par rapport à l'état de sa surface et à la contamination qui la recouvre. Sur une surface métallique propre et exempte de contamination organique, l'angle de contact d'avance avec une goutte d'eau est inférieur à 10°. Avec une molécule formant des couches monomoléculaires auto-assemblées (SAM : Self-Assembled Monolayers) montrant un groupe fonctionnel -OH (p.ex. HOC11H22SH), cet angle de contact est d'environ 30°, alors qu'il est d'environ 110° pour un groupe fonctionnel -CH3 (p.ex. C12H25SH) et d'environ 118 ° pour un groupe fonctionnel -CF3 (p.ex. C10F17H4SH).Surface energy is often determined by the last atomic or molecular layer. The chemical nature of the solid is of little importance in relation to the state of its surface and the contamination that covers it. On a clean metal surface free of organic contamination, the contact angle in advance with a drop of water is less than 10 °. With a self-assembled monomolecular layer (SAM) molecule showing a -OH functional group (eg, HOC 11 H 22 SH), this contact angle is about 30 °, whereas it is about 110 ° for a functional group -CH 3 (eg C 12 H 25 SH) and about 118 ° for a functional group -CF 3 (eg C 10 F 17 H 4 SH ).
Les techniques de fabrication utilisées en horlogerie laissaient jusque dans les années 1930 un état de surface minimisant l'étalement des lubrifiants par la présence d'un film abaissant l'énergie de surface (
Le dépôt d'un composé sur une surface fonctionnelle afin d'abaisser l'énergie de surface et de contrôler la mouillabilité et l'adhérence est un procédé assez répandu. Cependant, son application comme film barrière ou antimigration est limité à l'horlogerie (
Des produits à base d'acide stéarique dilué dans du toluène furent utilisés en horlogerie jusque dans les années 1970 (
Actuellement, la grande majorité des épilames disponibles sur le marché, comme le Fixodrop FK-BS de Moebius, ou la ligne des produits Fluorad (FC-722 et autres) de 3M, consistent en un polymère fluoré dissous dans un solvant perfluoré.Currently, the vast majority of epilams available on the market, such as Moebius' Fixodrop FK-BS, or the 3M Fluorad (FC-722 and others) line, consist of a fluorinated polymer dissolved in a perfluorinated solvent.
Le dépôt du composé sur le substrat s'effectue par trempage de celui-ci dans une solution de solvant perfluoré chargée en polymère. Le solvant utilisé est généralement du tétradécafluorohexane (C6F14) qui est, une fois volatilisé, un gaz à effet de serre puisqu'il reste stable 3200 ans dans l'air et a un potentiel à effet de serre de 7400 equ. CO2.The deposition of the compound on the substrate is carried out by soaking it in a solution of perfluorinated solvent loaded with polymer. The solvent used is generally tetradecafluorohexane (C 6 F 14 ) which, once volatilized, is a greenhouse gas since it remains stable for 3200 years in the air and has a greenhouse potential of 7400 equivalents. CO 2 .
L'invention a pour but de proposer des composés utilisables comme épilame pouvant être fixés à une surface de substrat solide.The object of the invention is to propose compounds that can be used as epilame and that can be attached to a solid substrate surface.
Ces buts sont atteints par l'invention telle que définie dans le jeu de revendications ci-joint.These objects are achieved by the invention as defined in the attached set of claims.
L'invention propose en effet une nouvelle couche ultra-mince hydrophobe et oléophobe formée par auto-assemblage sur une surface de substrat solide de composés à pied catéchol, et un procédé pour préparer cette couche ultra-mince qui utilise un solvant non fluoré, par exemple un mélange d'eau et de 2-propanol. Grâce au pied catéchol des composés utilisés, cette couche ultra-mince est solidement fixée à la surface du substrat solide. Cette couche ultra-mince présente des propriétés satisfaisantes pour une utilisation comme épilame, en particulier un angle de contact d'avance avec l'eau et un étalement d'une goutte d'huile, tout à fait comparables à celles de la couche obtenue à partir du produit commercial de référence Fixodrop FK-BS.The invention indeed proposes a novel ultra-thin hydrophobic and oleophobic layer formed by self-assembly on a solid substrate surface of catechol foot compounds, and a process for preparing this ultra-thin layer which uses a non-fluorinated solvent, by for example a mixture of water and 2-propanol. Thanks to the catechol foot of the compounds used, this ultra-thin layer is firmly fixed to the surface of the solid substrate. This ultra-thin layer has satisfactory properties for use as an epilame, particularly a contact angle in advance with water and a spread of a drop of oil, quite comparable to those of the layer obtained from the reference product Fixodrop FK-BS.

Pour être considéré comme épilame, c'est à dire empêcher de façon satisfaisante l'étalement d'huile, l'angle de contact d'avance avec l'eau doit être généralement d'au moins 100°. Sera également considéré comme épilame un film dont l'angle de contact peut être sensiblement inférieur à 100°, par exemple compris entre 90 et 100°, mais qui empêche néanmoins l'étalement, qui reste inférieur à 2 %.To be considered as epilame, that is to say to prevent the spread of oil satisfactorily, the contact angle in advance with the water must generally be at least 100 °. Will also be considered as epilame a film whose contact angle may be substantially less than 100 °, for example between 90 and 100 °, but still prevents spreading, which remains less than 2%.

On a dissout 23,4 mg de SuSoS1 (0,052 mmol) dans 80 ml de 2-propanol dans une fiole de 100 ml graduée. On a soumis la solution aux ultrasons (avec l'appareil Sonorex super 10 P à 100 %) jusqu'à dissolution complète. On a ajouté de l'eau ultrapure jusqu'à la marque de la fiole et secoué vigoureusement, ce qui a fait augmenter la température de la solution. Après retour de la solution à température ambiante, on a ajouté quelques gouttes d'eau pour ajuster le volume à 100 ml. On a soumis la solution aux ultrasons pendant 10 secondes pour la dégazer et permettre un mélange complet de l'eau et du 2-propanol.23.4 mg of SuSoS1 (0.052 mmol) in 80 ml of 2-propanol was dissolved in a graduated 100 ml flask. The solution was sonicated (with Sonorex super 10P 100%) until completely dissolved. Ultrapure water was added to the vial mark and shaken vigorously, which increased the temperature of the solution. After returning the solution to room temperature, a few drops of water were added to adjust the volume to 100 ml. The solution was sonicated for 10 seconds to degas it and allow complete mixing of water and 2-propanol.
Les échantillons d'or, d'acier poli, d'aluminium, d'oxyde de titane et de rubis ont été nettoyés dans une chambre UV/ozone pendant 30 minutes et immergés pendant une nuit dans la solution de SuSoS1. Les échantillons ont été ensuite immergés dans du 2-propanol pendant 10 secondes , rincés avec du 2-propanol et séchés avec un flux d'azote. Dans le cas de l'acier, les surfaces ont été légèrement polies avec une lingette imbibée de 2-propanol, rincées avec du 2-propanol supplémentaire et séchées avec un flux d'azote (voir Tableau 1A ci-après). OuThe gold, polished steel, aluminum, titania and ruby samples were cleaned in a UV / ozone chamber for 30 minutes and immersed overnight in the SuSoS1 solution. The samples were then immersed in 2-propanol for 10 seconds, rinsed with 2-propanol and dried with a stream of nitrogen. In the case of steel, the surfaces were slightly polished with a wipe impregnated with 2-propanol, rinsed with additional 2-propanol and dried with a stream of nitrogen (see Table 1A below). Or
Les mêmes échantillons ont été immergés pendant 12 heures à température ambiante dans une solution dans une solution de 0.5 mM de la molécule SuSoS1 dans un mélange d'heptane (96%) et de 2-propanol (4%). Les échantillons ont été rincés avec du 2-propanol et séchés sous un flux d'azote sec (voir Tableau 1B ci-après).The same samples were immersed for 12 hours at room temperature in a solution in a solution of 0.5 mM of the molecule SuSoS1 in a mixture of heptane (96%) and 2-propanol (4%). The samples were rinsed with 2-propanol and dried under a stream of dry nitrogen (see Table 1B below).

Les différents substrats utilisés sont
- des plaques de silicium recouverts d'une fine couche d'or
- des disques d'acier poli
- des disques de rubis poli
- des plaques d'aluminium
- des plaques de silicium recouverts d'une fine couche de dioxyde de titane

- polished steel discs
- polished ruby discs
- aluminum plates
- silicon wafers coated with a thin layer of titanium dioxide
Les principaux paramètres mesurés par VASE et CA sont rassemblés dans les Tableaux 1A et 1B ci-après.
L'analyse par spectroscopie de photoélectrons par rayons X (XPS) montre que les molécules SuSoS1 sont présentes sur toutes les surfaces par la détection des éléments N.X-ray photoelectron spectroscopy (XPS) analysis shows that SuSoS1 molecules are present on all surfaces by the detection of N elements.
Ces résultats montrent qu'on obtient sur tous les substrats testés une couche ultra-mince de SuSoS1.These results show that we obtain on all substrates tested an ultra-thin layer of SuSoS1.
Les valeurs d'angle de contact d'avance avec l'eau sont satisfaisantes pour une utilisation comme épilame (supérieures à 100° ou légèrement inférieures à cette valeur, mais avec des étalements inférieurs à 2% (comme on le verra plus loin.)Advantageous contact angle values with water are satisfactory for use as epilam (greater than 100 ° or slightly less than this value, but with smears less than 2% (as will be discussed later).
On revêt d'une couche ultra-fine de SuSoS1 des surfaces de substrats d'or, d'acier poli et de rubis comme décrit dans l'exemple 2. L'aspect de surface est excellent et on ne distingue aucune marque due au dépôt.An ultra-thin layer of SuSoS1 is coated with substrates of gold, polished steel and ruby as described in Example 2. The surface appearance is excellent and no markings can be distinguished due to the deposit .
On revêt d'une couche ultra-fine de Fixodrop FK-BS des surfaces de substrats d'or, d'acier poli et de rubis selon les indications du fabricant par trempage des substrats dans une solution de tétradécafluorohexane.An ultra-thin layer of Fixodrop FK-BS is coated with gold, polished steel and ruby substrates as specified by the manufacturer by dipping the substrates in a solution of tetradecafluorohexane.
L'épaisseur de cette couche mesurée par ellipsométrie sur l'or est de 1,0 nm pour SuSoS1 et 1,7 nm pour le Fixodrop.The thickness of this layer measured by ellipsometry on gold is 1.0 nm for SuSoS1 and 1.7 nm for Fixodrop.
On caractérise l'étalement des lubrifiants sur une surface en mesurant le diamètre moyen d'une goutte de typiquement 0,5 mm de diamètre immédiatement après dépôt de la goutte et après 20 minutes. L'étalement correspond à la variation relative du diamètre moyen après 20 minutes. Une bonne tenue d'un lubrifiant correspond à un étalement de 2% ou moins. Un étalement supérieur à 10% se remarque à l'oeil et n'est pas acceptable. L'huile utilisée pour les tests est une huile horlogère "941 "(maison Moebius et Fils, mélange d'alkyl-aryl-monooléate et de deux C10-C13 di-esters, viscosité de 110 cSt à 20°C, tension superficielle de 32.8 mN/m).The spreading of the lubricants on a surface is characterized by measuring the average diameter of a drop of typically 0.5 mm in diameter immediately after the drop has been deposited and after 20 minutes. The spread corresponds to the relative variation of the average diameter after 20 minutes. A good performance of a lubricant corresponds to a spread of 2% or less. Spreading greater than 10% is noticeable in the eye and is not acceptable. The oil used for the tests is a watch oil "941" (Moebius and Fils house, mixture of alkyl-aryl-monooleate and two C 10 -C 13 di-esters, viscosity of 110 cSt at 20 ° C, surface tension of 32.8 mN / m).
On compare l'étalement obtenu sur des surfaces d'acier, de rubis, d'aluminium, de dioxyde de titane, et d'or revêtues de la molécule SuSoS1, ainsi que d'une surface d'or revêtue du produit commercial Fixodrop FK-BS de la maison Moebius et Fils selon les indications du fabricant. Pour la molécule SuSoS1, l'étalement est en tous les cas inférieur à 2%, et est comparable à celui mesuré pour le Fixodrop, comme montré par le tableau ci-après.
Pour toutes les surfaces étudiées, l'angle de contact obtenu sur les couches ultra-minces réalisées avec la molécule SuSoS1 est supérieur à 100°, l'énergie de surface est inférieure à 20 mJ m-2, et l'étalement est inférieur à 2%.For all the surfaces studied, the contact angle obtained on the ultra-thin layers made with the molecule SuSoS1 is greater than 100 °, the surface energy is less than 20 mJ m -2 , and the spread is less than 2%.
Les couches résistent bien aux traitements de lavages sur rubis, aluminium, dioxyde de titane, mais moins bien sur or et acier.The layers are resistant to ruby, aluminum and titanium dioxide washings, but less well to gold and steel.
Les propriétés de la couche ultra-mince SuSoS1 sont au moins aussi bonnes que celles obtenues avec le produit commercial Fixodrop.The properties of the ultra-thin layer SuSoS1 are at least as good as those obtained with the commercial product Fixodrop.
