Patent ID: 8785013

Claim:
A composition comprising a mixture of (a) a polymer that consists essentially of (i) one or more monomers selected from the group consisting of tetrafluoroethylene, hexafluoropropylene, vinyl fluoride, vinylidine fluoride, trifluorethylene, chlorotrifluoroethylene, perfluoro(alkyl vinyl ether); and (ii) one or more monomers selected from the group consisting of (1) fluorinated vinyl ethers comprising perfluorinated side chains that comprise cation exchange groups selected from the members of the group consisting of carboxylate, phosphonate, imide, sulfonamide and sulfonimide groups; and (2) monomers comprising a side chain represented by the structure of the following Formula (IV) —(OCF 2 CFR 7 ) a —OCF 2 CFR 8 SO 3 X (IV) wherein R 7 and R 8 are each independently selected from F or a perfluorinated alkyl group having 1 to 10 carbon atoms, a =0, 1 or 2, and X is H, an alkali metal, or NH 4 ; and (b) one or more cyclofluoroalkylated fullerene compounds of Formula I (C 60+2n )(CF 2 CR 1 R 2 ) w R 3 x R 4 y R 5 z (I) wherein: R 1 is F; R 2 is OCF 3 , CF 3 , or Cl; R 3 is a perfluoroalkyl or perfluoroalkylether group; R 4 is a hydrocarbon alkyl or alkyl ether group; R 5 is H; n is an integer from 0 to 5; w is an integer from 1 to 15; x is an integer from 0 to 3+n; y is an integer from 0 to 3+n; and z is an integer from 0 to 3+n.
