Abstract

Large transverse strain S₁ responses with a high elastic strain energy density for stretched poly(vinylidene fluoride-trifluorethylene) (PVDF-TrFE) copolymer film are investigated under a proper electron irradiation treatment condition. Results showed a ratio of |S₁/S₃| larger that 1 where S₃ is the longitudinal strain which is in contrast with unstretched films which generate a relatively small transverse strain with a small ratio of |S₁/S₃| (approximately 0.25). It is also shown that in this copolymer system, the ratio of |S₁/S₃| can be varied over a broad range and that a large volume strain is observed in these films.
