    摘要: A piezoelectric film which is better in heat and deformation resistant properties than those in the prior art is provided along with a method of making the same. The film is a piezoelectric film that is composed of a copolymer of vinylidene fluoride and trifluoroethylene, the copolymer having a content of vinylidene fluoride in a range of not less than 82 mol % and not more than 86 mol % and having a molecular weight not less than 600,000. The piezoelectric film is subjected to a heat treatment for crystallization of the copolymer at a temperature ranging from not less than 140°C to not more than 150°C, and is thereby caused to develop piezoelectric property. The piezoelectric film is further characterized in that it has a heat resistance of not less than 140°C and a breaking distortion of not less than 8 % and not more than 55 %, and an excellent deformation resistant property.

    摘要: The invention relates to very high melt flow fluoropolymer compositions, having low melt viscosities. The fluoropolymers have low molecular weights of from 5 kDa to 200 kDa and melt viscosities of less than 2 kilopoise (kP) at 232° C. and 100 s−1. One use for the high melt flow fluoropolymers is in the formation of very small diameters fibers, useful for melt-blown non-woven materials. Fiber diameters of less than 9 microns, and preferably 500 to 2000 nm can be produced.
