Abstract :
The authors present DSC studies where heating and cooling rates and also thermal treatments were varied systematically. The results for 60/40 P(VDFTrFE) are presented in this paper which confirm the importance of thermal history and also show that samples with various configurations in terms of ferroelectric phases can be obtained in a somewhat controlled way via thermal treatment
