Abstract

Dielectric response of P(VDF/TrFE)(50/50) copolymer irradiated with 1 MeV electrons was studied under hydrostatic pressure. Pressure results in a nonlinear shift of the dielectric anomaly towards higher temperatures with the initial slope of the temperature of maximum losses dT_m/dp = 142 K/GPa. The contribution of polar clusters to the pressure behavior of the dielectric response is discussed.
