Thermally Simulated Current of Corona-Charged PVDF Film

코로나 대전된 PVDF 필름의 열자격 전류

It has been shown that the thermally stimulated current technique can be one of the most powerful methods for evaluating the electrical properties. An unstretched $\alpha$-form specimen of corona-charged, 50[${\mu}m$],t Polyvinylidene Fluoride shows four TSC peaks designated $\delta}$, $\gamma$, $\beta$ and $\alpha$ in assending order of temperature in temperature range $-100{\sim}200^{\circ}C$. The $\delta$, $\gamma$ peaks may be attributed to the dipolar depolarization in the amorphous regions and $\beta$, $\alpha$ peaks are associated with the detrap from trapped carriers in the crystalline regions.
