The influence of high-energy electron irradiation on the electrical properties of biaxially oriented polyvinylidene fluoride (PVF{sub 2}) film was investigated. The film was irradiated in air with a 1-MeV electron beam at a dose rate of 10 rad/min to different dose levels of up to 108 rad. Electrical properties measured included dielectric permitivity and dielectric loss, ac and dc breakdown voltages, and dc volume resistivity. X-ray diffraction and IR spectroscopy measurements were also made. The most pronounced of the radiation-induced changes were a decrease in ac breakdown voltage and an increase in dielectric loss, both corresponding to increasing total absorbed dose. DC breakdown changes are believed to be associated initially with radiation-induced crystal phase transformation. This was confirmed by X-ray diffraction curve and the IR spectra, which showed an increase in {beta}-phase and a decrease in {alpha}-phase peaks at higher dose levels.
