Abstract

Composition comprising a) a polymer comprising recurring units derived from vinylidene fluoride monomer and at least one monomer carrying at least one functional group selected from carboxyl groups, ester groups and hydroxyl groups, and b) a microporous adsorbent carbon material having a specific surface area (BET) of at least 700 m2/g, a pore volume in the range of from 0.1 to 0.7 m3/g, at least 60% of said pore volume being formed by micropores having a pore radius of 2 nm or less.
