1.前言1969年,日本小林理研公司的河合平司博士第一次发现了聚偏氟乙烯(PVDF)的压电性(物质当发生形变或受到应力时就会产生电极化,相反,当受到电场作用时就会产生形变和应力的一种性质)。自那以后,关于合成高分子压电性、热电性(物质随温度变化而极化程度也发生变化的一种性质)的研究很快就在世界上盛行起来。表1列出了有关压电性、热电性高分子研究的主要进展情况。 1. Introduction In 1969, Kobayashi Kawai, PhD, of Kobayashi R & D Co., Japan, for the first time discovered the piezoelectricity of polyvinylidene fluoride (PVDF), which produces electrical polarization when deformed or stressed. Conversely, When it will produce a deformation and stress of a nature). Since then, research into the piezoelectric and thermoelectric properties of synthetic polymers (a property in which the degree of polarization of a substance changes with temperature) is rapidly gaining ground in the world. Table 1 lists the major developments in piezoelectric and thermoelectric polymers.
