摘要：

In stretched poly(vinylidene fluoride) films, the transition from unpolar alpha -form to a polar form ( alpha //p) is produced by poling at 80 degree C by an electric field of 1 MV/cm. This oriented form has the same lattice constants as alpha -form but is associated with extra diffuse reflections. This form and the diffuse reflections disappear by annealing above 170 degree C and give an oriented and more stable form ( alpha prime ) in which the chain has the T//3GT//3G** minus conformation.
