要約(英語): Silica-agglomerate electrets on fluororesin film were fabricated by a charging just after spraying colloidal silica (SC) or mixed solution of colloidal silica and glycerin (MC) and pre-coating glycerin by electrostatic spraying before SC (GSC) to compare the electret by electrostatic spraying colloidal silica (ES). The tiny silica agglomerates were not observed on the electrets when the charging was done just after spraying solutions. Eventually, the charge retention at 250℃ of SC, MC and GSC was higher than that of ES. Furthermore, the silica-agglomerate with small height of MC and GSC also demonstrated the excellent charge retention and the MC sample with 22μm of height kept -0.77kV of the surface electric potential after heating to 250℃.
