摘　　要：以蔗糖、蒙脱石为原料，在超声分散条件下，采用溶液插层、碳化方法制备插层型碳／蒙脱石纳米复合材料，通过X射线衍射（XRD）和红外光谱（FFIR）等分析表征方法对插层型蔗糖／蒙脱石纳米复合材料、碳／蒙脱石纳米复合材料进行表征，XRD结果表明，在400W的超声及70℃下，按蒙脱石：蔗糖：蒸馏水=1：2：20的比例超声反应2h，静置2h后能够得到d001=1．80nm的蔗糖／蒙脱石复合材料；将其在400℃氮气氛中碳化3h能够得到d001=1．34nm的复合材料。FTIR谱图表明，蔗糖／蒙脱石复合材料碳化完全，最终获得了具有三明治结构的碳／蒙脱石纳米复合材料。The intercalated carbon-montmorillon composites are prepared by solution intercalation ,carbonization under the ultrasonic dispersion with sucrose and montmorillon as raw materials.The composites are characterized by XRD, FTIR. The results show that the composites which d001=1.80nm are made when the ratio of MMT：sucrose：H2O=1：2：20 under the condition of 400W at 70℃ for 2 hours and indicate that the sucrose/MMT which d001=1.80nm can be carbonized into C/MMT composites with d001=1.34nm under 400℃ at nitrogen atmosphere.As the disappearing of methyl and methy- lene confirmed by FTIR,the sucrose/MMT composites have been carbonized completely and the C/MMT nanocomposites which have the structure like sandwich are obtained.
