Abstract:
A composite material comprising, by weight, the total being 100%:A) 40 to 90% of a polyvinylidine fluoride (PVDF) homopolymer or copolymer crystallized essentially in the &bgr; form, B) 10 to 60% of a conductive filler, C) greater than 0% but not more than 40% of either a polyvinylidene fluoride homopolymer or copolymer which is not crystallized in the &bgr; form or a vinylidene fluoride-hexafluoropropylene copolymer (VF2-HFP) comprising at least 85 mol % of VF2, D) 0 to 40% of a filler other than C, such that the crystals in the &bgr; form are nucleated on the surface of the conductive filler.
