摘要: This paper reports on an investigation of the effects calcination structure and dielectric properties polyethylene/silica (SiO 2 ) nanocomposites. Calcination temperatures 600 900 °C have been used in order to modify surface chemistry SiO . The results show that, after calcination, concentration hydroxyl groups water molecules around within resulting nanocomposites is reduced. real permittivity containing calcined decreases compared based uncalcined DC breakdown strength becomes higher than those In contrast, AC was found not be significantly affected by addition any silicas considered here. use nanofillers can positive akin chemically functionalized enhancing nanocomposites; both approaches remove polar groups.
