Piezoelectric Polymers

Abstract

The objective of this program was the development of improved fluoropolymer resins for transducer applications. The effort involved synthesis, characterization, and processing of new resins with emphasis on those obtained by copolymerizing vinylidene fluoride (VF2) with monomers such as tetrafluoroethylene (TFE), vinyl fluoride (VF), trifluoroethylene (VF3), and hexafluoropropene (HFP). Variations on the PVF2 homopolymer synthesis were also investigated. In a number of cases the piezoelectric activity of the copolymers was found to be as good or better than that of the PVF2 homopolymer; however, a distinct advantage of the copolymer vs homopolymer is the fact that, in general, the copolymers are considerably easier to fabricate into thick, oriented film configurations, as needed for underwater use.
