Preparation of Epoxy Resin/montmorillonite Composites by Monomer Insert In-situ Polymerization

摘要

Epoxy resin/ montmorillonite (EP/MMT) composite was prepared via monomer insert in-situ polymerization. It was shown that the EP/MMT composites could be successfully synthesized from the raw materials only by one step, making it simpler than traditional in-situ intercalative polymerization method. The d_(001) spacing of montmorillonite was tested by XRD and increased to 4.30 nm. The results showed that tensile strength and impact strength were improved by 98.11 and 93.69%, respectively. The glass transition temperature was increased by 17.3°C.
