Disclosed is a method of preparing a modified halogenated polymer surface, comprising the steps of (a) activating the surface by modification with a polymerisation initiator by (a1) reacting the halogenated polymer surface with sodium azide, subsequent (a2) patterning the azidated surface via photolithographic patterning methods, and subsequent (a3) 1, 3 dipolar cycloaddition with an alkine-functionalized initiator; and (b) reacting the activated surface obtained in steps (a1)-(a3) with polymerizable monomeric units A and/or B.

L'invention porte sur un procédé de préparation d'une surface polymère halogénée modifiée consistant à (a) activer la surface par modification avec un amorceur de polymérisation par (a1) réaction de la surface polymère halogénée avec de l'azide de sodium, puis (a2) formation de motif sur la surface azidée par des procédés photolithographiques de formation de motif, enfin (a3) cyclo-addition 1,3 bipolaire avec un amorceur à fonction alcyne ; et (b) réaction de la surface activée obtenue aux étapes (a1) à (a3) avec des unités monomères polymérisables A et/ou B.
