Abstract

In this paper, the effects of electron beam irradiation on dielectric constant (ε_r), dissipation factor (tanδ), thermally stimulated current (TSC) and conduction current of polyetheretherketon (PEEK) were investigated. ε_r and tanδ of irradiated PEEK started to change from a higher temperature than unirradiated material. The peak temperature of TSC increased with increasing dose. Conduction current of irradiated PEEK became smaller than that of unirradiated material. The crosslinking of molecules caused by the electron beam irradiation affected the electrical properties
