传统上在某些单晶和陶瓷中遇到的压电性和热电性，现在也在许多聚合物中有记载。最近，一种这样的聚合物-聚（偏二氟乙烯）-和它的一些共聚物已被证明是铁电的。详细讨论了聚合物中铁电行为的特殊分子和超分子结构要求，特别强调了聚偏氟乙烯。压电，热释电和铁电性能也简要回顾，因为是这样的聚合物的一些有前途的应用。
Piezoelectricity and pyroelectricity, traditionally encountered in certain single crystals and ceramics, have now also been documented in a number of polymers. Recently, one such polymer—poly(vinylidene fluoride)—and some of its copolymers have been shown to be ferroelectric as well. The extraordinary molecular and supermolecular structural requirements for ferroelectric behavior in polymers are discussed in detail, with particular emphasis on poly(vinylidene fluoride). Piezoelectric, pyroelectric, and ferroelectric properties are also briefly reviewed, as are some promising applications of such polymers.
