Electrical characteristics of electron beam irradiated PEEK
Description
In this paper, the effects of electron beam irradiation on dielectric constant (/spl epsiv//sub r/), dissipation factor (tan/spl delta/), thermally stimulated current (TSC) and conduction current of polyetheretherketon (PEEK) were investigated. /spl epsiv//sub r/ and tan/spl delta/ 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.
