Electrical, Thermal, and Tensile Properties of Cycloaliphatic Epoxy/Carbon Black and Cycloaliphatic Epoxy/Fumed Silica Nanocomposites

摘要

Carbon black and fumed silica have previously been shown to reinforce polymer nanocomposites. Their effects on electrical and thermal properties are also of interest for potential use in high voltage and temperature applications. Cycloaliphatic epoxy is examined in this study because of its resistance to aging. The objective of this study was to determine the effects of adding 0.5 to 2 wt% carbon black or 1 to 4 wt% fumed silica to cycloaliphatic epoxy. Electrical conductivity, thermal conductivity, tensile properties, and glass transition temperature as determined by dynamic mechanical analysis were tested. The results of these tests showed that up to 2 wt% carbon black or 4 wt% fumed silica had little effect on the electrical, thermal, or tensile properties of cycloaliphatic epoxy.
