A method for modifying the surface energy of at least one surface of a solid is provided. The method may comprise a step consisting of grafting, on the surface, a polymeric organic film consisting of graft polymers, each polymer having a first unit bound directly to the surface derived from a cleavable aryl salt and at least one other unit of the polymer chain derived from a component selected from the group consisting of a cleavable fluorinated aryl salt, a fluorinated (meth)acrylate and a vinyl-terminated siloxane. In addition, a kit for implementation of the method is provided.

Method for modifying the surface energy of a solid

The present invention relates to a process for assembling at least one zone of a first surface with at least one zone of a second surface or with a molecule of interest, comprising a step that consists in placing the said zone of the said first surface in contact with the said zone of the said second surface or with the said molecule of interest, the said zone of the said first surface bearing at least one radical and/or ionic species. The present invention also relates to a solid support whose surface bears at least one zone with at least one radical and/or ionic species, with at least one adhesion primer, or with at least one adhesion primer precursor, and to its various uses.

Process for assembling two surfaces or one surface with a molecule of interest

The present invention relates to a process for the preparation of an organic film on a portion of the surface of a solid support made of (co)polymer, characterized in that it comprises the successive steps consisting in (i) subjecting said surface portion to an oxidizing treatment and (ii) grafting an organic film to said surface portion by radical chemical grafting.
