Abstract
Regular changes in ferroelectric and pyroelectric properties of P(VDF-TrFE) polymer thin films were observed when the films have a bent-deformation caused by external force. The deformation rate dependence of the remanent polarization, relative dielectric constant and pyroelectric coefficient of the P(VDF-TrFE) thin films were studied. The results demonstrated that there was an increase of ∼12.2% in the remanent polarization of the bent films between the maximum and the minimum bent-deformation rate. Pyroelectric coefficient of the bent P(VDF-TrFE) thin films was also enhanced compared with the flat P(VDF-TrFE) films. P(VDF-TrFE) films can still maintain good performance in ferroelectric and pyroelectric properties under bent deformation, which is meaningful to the potential application in flexible devices.
