Pyroelectricity in graphene oxide doped P(VDF-TrFE) films

The pyroelectric properties of polyvinylidene fluoride/trifluoroethylene doped with graphene oxide were studied. The pyroelectric current measurements were performed for polarized and non-polarized samples with different amount graphene oxide: 5, 10, 15, 20, 25%. The polarization process influence on pyroelectric current was discussed. Moreover the impact of different amount of dopant on pyroelectric properties of polyvinylidene fluoride/trifluoroethylene was analyzed. On the basis of obtained results the phase diagram was performed.
