Effect of the nature of clay on the thermo‐mechanodynamical and electrical properties of epoxy/clay nanocomposites

Abstract

The effect of nature of clay on the thermo–mechanodynamical and electrical properties of epoxy/clay nanocomposites prepared from bisphenolic epoxy resins and different nanoclays are presented. The thermal–mechanodynamical properties of the nanocomposites were studied by DMTA, showing significant increase in both elastic modulus and glass transition temperature. Short time AC dielectric breakdown strength measurements carried out on the nanocomposites showed an increase in dielectric breakdown strength for the nanocomposites prepared with organically modified clays. The space charges accumulated in the materials as studied by pulsed electroacoustics method showed a significant decrease in the space charge accumulation in the nanocomposites with organoclays as the nanofiller. Similarly the space charge decays almost completely in the nanocomposites prepared with organoclays as nanofiller. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers

Influences of clay and manufacturing on fire resistance of organoclay/thermoset nanocomposites

“…Most of them were interested in the mechanical, electrical and thermal properties [20][21][22][23]. Other studies [24][25][26][27][28] discovered the enhancing effect of nanoclay/organo-modified clay on the fire performance of thermoplasticbased composites.…”
