Electro-Physical Properties of Composites with Nano-Sized Oxides
Polymer matrix nano-sized oxide composites were fabricated by using a modified injection molding in which nano-sized silicon oxide and nano-sized magnesium oxide were contained. Thermal decomposition and evaporation of organic resin depended on the composition of the composites. Nano-sized
oxides were uniformly distributed in the composites produced by a modified injection molding combining vacuum degassing and curing at a moderate temperature. 0.2 wt.% of silicon oxide addition to epoxy resin showed the maximum electric field of 3.6, whereas, 2.0 wt.% of magnesium oxide addition
was required to reach the same value of electrical field. Both of thermal conductivity and thermal diffusivity of the nano-sized silicon oxide-epoxy composites tended to be increased with silicon oxide content. The relative permittivity of the nano-sized silicon oxide-epoxy composites increased
from 5.16 to 5.31 by adding 0.6 wt.% silicon oxide, whereas, magnesium oxide addition up to 2.0 wt.% little influenced to the permittivity. Epoxy matrix-nano-sized silicon oxide composites were more suitable than magnesium oxide for the high performance capacitance.
