ABSTRACT:
A porous or non-porous polymeric substrate having its surface modified with an immobilized fluorocarbon such as perfluorocarbon, polymeric composition is provided. The immobilized fluorocarbon is formed from a monomer having formula: [T—SO2Y—SO2T′]−M+in which —T and T′ are identical or different and comprise an organic radical bearing at least one active polymerization function such as an unsaturation or a ring that can be opened; —M+comprises an inorganic cation. —Y comprises N or CQ in which Q comprises H, CN, F, SO2R3, substituted or unsubstituted C1-20alkyl, substituted or unsubstituted C1-20aryl, substituted or un-substituted C1-20alkylene, in which the substituent comprises one or more halogens, and in which the chain comprises one or more F, SO2R, aza, oxa, thia or dioxathia substituents; and —R3comprises F, substituted or unsubstituted C1-20alkyl, in which the substituted or unsubstituted C1-20aryl, substituted or unsubstituted C1-20alkylene, in which the substituent comprises one or more halogens.
