摘要

The dielectric relaxation properties of ~(60)Co γ-ray irradiated Poly(vinylidene fluoride) (PVDF) have been investigated. The structural changes of irradiated PVDF were analogized using DSC analyses. Cole-Cole's circular arcs were induced from the results of the temperature and frequency dependency of dielectric properties with increasing radiation dose. The values of relaxation intensity calculated using Cole-Cole's circular arc can be useful for evaluation of the radiation degradation level of PVDF.
