摘要：

We present an extensive characterization and modeling of the use of a polyvinylidene fluoride trifluoroethylene copolymer P(VDF-TrFE) as a photo activated actuator. P(VDF-TrFE) copolymers are very appealing for applications because, on the opposite of the PVDF homopolymer, which requires a drawing or stretching followed by annealing and poling process to show ferroelectric properties, they spontaneously crystallize to beta phase. Based on the measurement of the bending of P(VDF-TrFE) strips under illumination, we extrapolated a model of the role of temperature, piezoelectric effect, and photostrictive components.
