## Abstract This report describes isothermal aging of piezoelectricity in poly(vinylidene fluoride) (PVDF) based on longβterm heat treatments between 40 and 160Β°C. The results demonstrate that no piezoelectric decay occurs below about 60Β°C, that between 60 and 160Β°C the aging behavior follows logar
The ferroelectric and piezoelectric properties of melt-quenched unoriented poly(vinylidene fluoride-trifluoroethylene) (73 : 27) copolymer films as a function of the number of poling cycles have been studied. The investigation revealed that quenched films exhibit a decrease in D-E hysteresis behavio
