Fluoropolymer/fluorine-containing organopolysiloxane composite material, method for producing same, use of same, and precursor composition used in said production method

Abstract

Provided are a novel composite material in which a fluoropolymer and a fluorine-containing organopolysiloxane are dispersed in a mutually inseparable state, a method for producing the same, use of the same, and a precursor composition. The fluoropolymer-fluorine-containing organopolysiloxane composite material comprises: (A) one or more fluoropolymers selected from the group comprising polyvinylidene fluoride and polyvinylidene fluoride copolymers; (B) an organopolysiloxane crosslinking reaction product having a fluorine atom-containing organic group, obtained by subjecting to a crosslinking reaction a reactive organopolysiloxane having a fluorine atom-containing organic group and one or more reactive functional groups in the molecule capable of crosslinking between molecules by the reaction of these reactive functional groups; and optionally (X) fillers and/or other additives besides component (A) and component (B). Components (A) and (B) are included such that the mass ratio ((A)/(B)) of component (A) and component (B) is in the range of from 99/1 to 60/40.

Dependencies are inferred from the claim text.
