The piezoelectric property of thick P(VDF-TrFE) copolymer films could be enhanced by a two-step thermal poling method. Two weak resonance peaks were observed after the first poling, while only a single strong resonance was found after the two-step poling process. To study the mechanisms of the polarization process, X-ray diffraction (XRD) and differential scanning calorimetry (DSC) were used. The results were reported.
