一、概况 所谓“压电塑料”,简言之就是“具有压电效应的塑料”。它是以具有电荷分布不对称中心的结晶高分子化合物为主体的柔性压电材料(本文只讨论人工合成的压电高分子化合物的某些问题,而不讨论天然高分子的压电性)。当它们受到一定的应力(压 First, the overview The so-called “piezoelectric plastic”, in short, is “a piezoelectric effect of plastic.” It is a flexible piezoelectric material mainly composed of crystalline macromolecular compounds with asymmetric charge distribution center (this article only discusses some problems of synthetic piezoelectric polymers, but not the piezoelectricity of natural polymers). When they are subjected to a certain amount of stress (pressure
