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

摘要

The invention relates to a process for preparing a composite material comprising a fluorinated polymeric matrix and a filler consisting in ion exchange inorganic particles comprising a step for in situ synthesis of said particles within the polymeric matrix, said matrix comprising at least one first copolymer comprising at least two types of fluorinated recurrent units, a type of which bears at least one pendant maleic anhydride group.
