METHOD FOR PREPARING AN ION-EXCHANGE COMPOSITE MATERIAL COMPRISING A POLYMER MATRIX AND A FILLER CONSISTING OF ION-EXCHANGE PARTICLES

摘要

The invention concerns a method for preparing a composite material comprising a fluorinated polymer matrix and a filler consisting of inorganic ion-exchange particles comprising a step of in situ synthesis of said particles in the polymer matrix in the presence of a compatibilising agent consisting of a copolymer comprising a first repetitive pattern resulting from the polymerisation of a fluorinated ethylene monomer and a second repetitive pattern resulting from the polymerisation of an optionally fluorinated (meth)acrylic monomer, said first repetitive pattern being different from said second repetitive pattern and said copolymer being different from the (co)polymer or (co)polymers that make up the fluorinated polymer matrix.
