1. A composition comprising a blend of fluorinated electroactive polymers, said blend being composed of:
a) at least one fluorinated terpolymer of formula P(VDF-X-Y) comprising units derived from:
vinylidene fluoride (VDF),
units derived from a monomer X, X being trifluoroethylene (TrFE), and
a third monomer Y chosen from either chlorotrifluoroethylene or 1,1-chlorofluoroethylene, wherein the units derived from the monomer Y contribute from 1 to 15 mol % towards the sum of units of the at least one fluorinated terpolymer; and
b) at least one copolymer of formula P(VDF-TrFE) comprising units derived from vinylidene fluoride and units derived from trifluoroethylene, the proportion of units derived from trifluoroethylene being greater than 50 mol % relative to the sum of the units derived from vinylidene fluoride and trifluoroethylene.
