摘要：
Tn order to investigate the piezoelectric properties of composite films of 0.91Pb(Zn1/3Nb2/3)O-3-0.09PbTiO(3) (PZNT) and polyvinylidene fluoride (PVDF) prepared by the sol-gel method in comparison with those of PVDF, copolymers of vinylidene fluoride and trifluoroethylene (P(VDF/TrFE)), and polyurea-5, the residual polarization P-r and the electromechanical coupling factor k(33) were measured. The results verified that PZNT- and PVDFcomposite-firm (PZNT/PVDF film) manufacturing method can effectively realize a uniformly large area composite membrane. We obtained the apparent P-r of PZNT/PVDF film in D-E hysteresis measurements. The k33 value of the PZNT/PVDF film is about 0.08. The k(33) value is approximately 1/4 that of the beta -PVDF or P(VDF/TrFE) film.
