摘要：

Dynamical response to an applied electric and heat field is important in pyroelectric application of polymers, particularly due to their complex heterogeneity. We studied the effect of nonuniform poling of PVDF film on the dielectric and pyroelectric behaviour. Heterogeneous distribution of polarization results in pyroelectric coefficient anomaly in the frequency range 10(2) - 10(4) Hz observed when the electrode grounded during poling, is illuminated. The effect of the crystalline heterogeneity of the samples on the dielectric behaviour (beta - relaxation) is apparent in the MHz range at room temperature.
