Abstract

See full text

The invention relates to inorganic particles which are covalently bonded to first polymer chains made up of at least one polymer carrying proton exchange groups, optionally in the form of salts, and bonded to second polymer chains made up of at least one fluorinated polymer that does not carry any proton exchange groups, the second chains being bonded to the particles via organic spacer groups, or the second chains being bonded to first chains via organic spacer groups, or some of the second chains being bonded to the particles via organic spacer groups while the remaining second chains are bonded to first chains via organic spacer groups.
