要約(日本語): This paper investigated the dielectric properties of doped fluorine into a PP matrix by melt-blending of iPP with small additions of PVDF. The specimens used in the experiments were Pristine PP, 0.01 wt% PVDF doped iPP, and 3.0 wt% PVDF doped iPP. Samples sputtered with gold on both sides. Dielectric properties were measured by applying an AC voltage of 10 V and 0.1 Hz to 10 MHz. Temperature conditions were set from 30℃ to 150℃. In the real part of permittivity, all specimens showed a tendency to decrease with increasing temperature and showed a tendency to be constant with increasing frequency. _x000D_ In AC conductivity, it was observed that Pristine PP and 0.01 wt% PVDF doped iPP had a decreasing trend with increasing temperature below 1 kHz, but the decreasing trend decreased at 3.0 wt% PVDF doped iPP.
