Abstract:Ca montmorillonite was directly modified with hexadecyl trimethyl ammonium bromide. The interlamellar spacing of the organophilic montmorillonite (O MMT), corresponding to the (001) plane peak reached 2.21 nm. The reaction process of the curing system (E 51/BADK/MMT) was studied by non isothermal DSC and carefully analyzed. Based on the Kissinger method, the apparent activation energy (ΔE) was calculated to be 41.03 kJ/mol. The reaction order(n=0.85) was calculated according to Crane theory. The curing reaction conditions with BADK as the curing reagent were found. At last, the thermal properties of epoxy resin/MMT nanocomposites were studied by non isothermal DSC. The experimental data indicate that Tg’s of nanocomposites are higher.
