Abstract

As a part of the fundamental study of the relaxational behaviour of the semi-crystalline polymer polyvinylidene fluoride (-(CH₂-C₂)_n-, PVDF), thermally stimulated depolarization (TSD) measurements have been carried out on γ-irradiated thin films, poled in vacuo. Following irradiation, the total TSD relaxation strength below room temperature is depressed. Mathematical analysis of this region of the TSD spectrum reveals the reduction to be caused by the decrease of the β-(glass-transition) relaxation peak. One also observes the irradiation-induced creation of two relaxation peaks, both with higher activation energies than their neighbours. Tentative interpretations for the different components of the relaxation spectrum are proposed.
