Abstract

A type of micro-multilayer particles with a structure similar to that of nacre was prepared by poly(oxypropylene) diamine (POPD) intercalating organic montmorillonite (OMMT). The prepared particles were then blended with epoxy resin (EP) to obtain high performance EP composites. The Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis and contact angle analysis of the OMMT showed that the (POPD) had been successfully intercalated into the OMMT and the micro-multilayer particles were obtained as expected. Transmission electron microscope observation of the cured composites further confirmed that the micro-multilayer particles were well maintained in the EP network. The tensile and bending strength and glass transition temperature of the OMMT/EP composites were all increased compared with those of the EP. All these showed that the addition of the OMMT was an effective way to obtain high performance EP composites.
