Intercalates formed by contacting a layered material, e.g., a phyllosilicate, with an intercalant onium ion spacing agent and an anhydride- curable epoxy resin. The intercalant onium ion spacing agent converts the interlayer region of the layered materials from hydrophilic to hydrophobic, therefore, the anhydride-curable epoxy resin can be easily intercalated into the interlayer spacing. The co-presence of the co-intercalant anhydride-curable epoxy resin in the interlayer space provides surprising increase in glass transition temperature for anhydride-curable epoxy resin matrix polymer/co- intercalant compounded nanocomposites. The nanocomposites (e.g., epoxy-clay) prepared from the intercalants demonstrate enhanced mechanical, thermal and chemical resistance compared with pristine polymer matrices.
