摘要：The imprint behaviors for poly(vinylidene fluoride-trifluoroethylene) (P(VDF-TrFE)) copolymer ultrathin films with electroactive interlayers have been studied. The different electroactive polymers are used as the interlayer between P(VDF-TrFE) and metal electrodes. It is found that the smaller voltage shift is observed for the samples with electroactive interlayers and the imprint properties are improved substantially after the electroactive interlayers are introduced. The charge trap accumulation in P(VDF-TrFE) films without and with interlayers is analyzed and it is thought that the traps would be partially compensated by the free charges from the electroactive interlayers, illustrating the importance of the appropriate interlayer materials.
