Proton radiation effects on poly(vinylidene fluoride-trifluoroethylene) copolymer were investigated. It was observed that the electrical-field induced strain response followed a quadratic electrostriction relationship, after the proton bombardment. It was found that the copolymer showed relaxor ferroelectric behavior. A reduction in the polarization hysteresis was observed after the proton irradiation. The results show that electromechanical properties of the copolymers got improved after the proton irradiation.
