摘　　要：The direct exfoliation of in situ intercalative copolymerized styrene/maleic anhydride charge-transfercomplex(PSMA)into the inter lamellar spaces of modified kaolin(Kao-DMSo),which WaS intercalated and surfacemodified by dimethyl sulfoxide (DMSO),WaS reported.The nano structure of the composites WaS investieated by wide-angle X-ray diffraction (XRD) and transmission elec-tron microscopy(TEM).The interaction between kaolin surface and PSMA chain WaS conformed by FTIR analysis.The XRD results showed that the intercalated polvsty-rene-malelc anhyvdride units were arranged in the flattened monolayerarrangements.and the 001 diffraction peak of the origlnal kaolin disappeared.The TEM image showed that the kaolin WaS exfoliated into nanometer size and dispersed in the polymer matrix.Additionally the thermal stability of the nanocomposites was studied by thermo-gravimetric analysis (TGA),and the resulting thermogram indicated that the thermal stability of the nanocomposites WaS significantlyThe direct exfoliation of in situ interealative copolymerized styrene/maleicanhydride charge-transfer-complex (PSMA) Into the inter lamellar spaces of modified kaolin(Kao-DMSO), which was intercalated and surface modified by dimethyl sulfoxide (DMSO), was reported.The nano structure of the composites was investigated by wide-angle X-ray diffraction (XRD) andtransmission electron microscopy (TEM). The interaction between kaolin surface and PSMA chain wasconformed by FTIR analysis. The XRD results showed that the intercalated polystyrene-maleicanhydride units were arranged in the flattened monolayer arrangements, and the 001 diffraction peakof the original kaolin disappeared. The TEM image showed that the kaolin was exfoliated intonanometer size and dispersed in the polymer matrix. Additionally the thermal stability of thenanocomposites was studied by thermo-gravimetric analysis (TGA), and the resulting thermogramindicated that the thermal stability of the nanocomposites was significantly increased.
