The invention relates to a fluorocarbon polymer material comprising a main chain with the following unit: in which: Z is a quaternary ammonium group, Y1 and Y2 are each independently an oxygen or sulfur heteroatom, A is a linear, fluorinated or perfluorinated, having from 2 to 6 carbon atoms, R 1 represents a phenyl group, an aryl group or a -CR 2 R 3 - group and R 4 is chosen from the group consisting of a hydrogen atom, a linear or branched halogenated alkyl or alkyl group, cyclic or acyclic and a group represented by the following formula (3): m is an integer between 0 and 10, preferably between 0 and 3; m ', n and r are integers each independently of 0 or 1; and s is 0 or 1 with the proviso that when s is 0 then R4 is different from the hydrogen atom. |
