Electrical behavior of epoxy resin subjected to thermal treatment by temperature variation

This paper analyzes the behavior of some epoxy resin samples subjected to thermal treatment through temperature variation. After being prepared, the polymeric material was subjected to a temperature variation from +150(o)C to -20(o)C during 10 cycles. The effect of thermal cycles on epoxy resin samples was studied with the help of FTIR, SEM, XRD, UV-Vis, electrical, and dielectric measurements. The results show that the thermal treatment to which the samples are subjected produces changes in their structure and morphology and affects the electrical and dielectric properties of the studied epoxy resin.
