[摘要]：The effect of hydrostatic pressure on the dielectric response of P(VDF/TrFE)(50/50) irradiated with fast electrons has been studied. A non-linear upward shift of the glass transition temperature T-g and the Curie temperature T-C of the polymer relaxors was observed under pressure with the initial slope dT(g)/dp being considerably smaller than dT(C)/dp. Moreover, pressure was found to reduce the contribution to the low-frequency dielectric absorption originating from segmental motions in the amorphous phase whereas the contribution related to ferroelectric-paraelectric transition and that of polar nanoclusters in the crystalline phase were found to be enhanced.
