Abstract: Ca-montmorillonite was directly modified by ion-exchang method using hexadecyl trimethyl ammonium bromide. The interlamellar spacing of the montmorillonite, corresponding to the(001) plane peak, increases from 1.49 nm for the purified MMT to 2.21 nm for the organophilic clay(C16-MMT). The epoxy resin/BADK/MMT nanocomposites were prepared. The effects of content of montmorillonite and mixing conditions including mixing temperatures and mixing time on the intercalation and exfoliation behavior of epoxy/alkylammonium-montmorillonite nanocomposites after curing with curing agent(BADK) were investigated by X-ray diffraction(XRD). The X-ray patterns reveal that organoclay was intercalated by the epoxy resin during mixing process. When E51 was cured with equimolar amounts of BADK, either an intercalated or an exfoliated nanocomposites were obtained. Only under certain mixing conditions, the exfoliation nanocomposite materials could be formed.
