Abstract

We report the discovery of a compressibility phase transition at 160 K in crystalline copolymer films of vinylidene fluoride ( $70%$) with trifluoroethylene ( $30%$). This phase transition is distinct from the known bulk ferroelectric-paraelectric phase transition at 353 K and surface ferroelectric ...
