A Study of the Mechanism of Pyroelectricity in Polymer Films.

Abstract

A study was undertaken of both theoretical and experimental aspects of the phenomenon of pyroelectricity in polymer films, focussing on polyvinylidene fluoride. Four theoretical models were considered in detail: a 'rigid rod' model; a 'perimeter of separation' model; a 'molecular rearrangement' model; and a 'space charge' model. Experimental studies developed some methods which may be useful in obtaining mechanistic information, and also determined that a copolymer of vinylidene fluoride and tetrafluoroethylene had a significantly larger pyroelectric coefficient than polyvinylidene fluoride homopolymer.
