Electrical Properties of Ultra-Sonicated Epoxy Resin

Abstract

As ultra-sonication is a mostly used method to disperse the particles into the polymer matrix, the aim of this study is to point out the effect of epoxy’s exposure to ultra-sounds over the electrical properties, especially the electrical conductivity. As the epoxy resins are insulators, the method is based on the determination of electrical conductivity via the measurement of electrical insulation resistance. The polymer solution was exposed for 45 minutes to ultra-sounds produced by one, two, three and four generators at different values of ultra-sounds frequency.
