Definitions

  • the present invention relates, on the one hand, to a support receiving molecules having an activity, either against unwanted organisms or phenomena, or in favor of a desired phenomenon, on the other hand, at a method of ensuring the presence of these molecules at such a support and, secondly, a composition for implementing this method and / or to be associated with said support.
  • the invention relates to the field of media processing and will find its application when it comes to making media that have particular properties, particularly in the context of the protection of this support or an element receiving such a support, against adverse effects.
  • a first method consists in ensuring the fixing of molecules on a support by making a covalent bond between this support and these molecules. Such is, for example, the case when it comes to fixing coloring molecules on a support, in particular cellulose.
  • Such a method has a number of disadvantages in that the realization of a covalent bond, on the one hand, requires the intervention of specific chemicals and a substantial supply of energy and on the other hand and above all, causes an irreversible chemical modification of the support as well as the structure and the activity of the molecules which is not admissible.
  • Another method is to ensure the attachment of molecules on a support by bonding these molecules with a binder.
  • Such bonding is, in fact, achieved by polymerization of this binder at high temperature which has a number of disadvantages consisting, on the one hand, in a stiffening of the support and, on the other hand, in a flooding of the molecules. within the binder which makes these molecules completely inactive.

  • Yet another advantage of the invention is that this method makes it possible to envisage, without destruction or inhibition, the fixation of many different types of molecules having activity in many fields, this on a large amount of supports of various nature and varied.
  • An additional advantage relates to the fact that the active molecules can be arranged in the form of superimposed layers that can be removed successively (in particular by mechanical or chemical effect such as, for example, by washing, by friction or other support) which, d on the one hand, allows to maintain the activity of the support and, on the other hand, allows activation successive molecules identical or different (for example for a different action) trapped at said support.
