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.
