石墨烯具有独特的纳米结构和一系列极具吸引力的特性,成为新型纳米复合材料的理想载体,如纳米复合材料分散的基体.提出了一种以石墨,苯胺,四氯化锡为原料制备石墨烯/二氧化锡/聚苯胺的新方法.通过X-射线衍射,红外光谱,透射电子显微镜,扫描电子显微镜以及紫外-可见光谱对合成的材料进行表征.结果表明：二氧化锡纳米粒子原位吸附在石墨烯的表面,有效地避免了石墨烯片的堆叠,聚苯胺加入后可大大提高二氧化锡的电化学性质.

Graphene sheets,which possess unique nanostructure and a variety of fascinating properties,can be considered as promising nano-scale building blocks of new composites,for example,a support material for the dispersion of nano-composites.A general approach for the preparation of graphene/SnO2/polyaniline nano-composites using aniline,graphite and tin tetrachloride as building blocks was presented.The as-synthesized composites were characterized by X-ray diffraction,Fourier transform-infrared spectroscopy,transmission electron microscopy（TEM）,scanning electron microscopy（SEM）and ultraviolet–visible spectroscopy.The results show that the situ-formed SnO2 nano-particles are adsorbed on graphene oxide sheets to form a film-like composite and as a result,the restacking of the as-reduced graphene sheets is effectively prevented.The SnO2/polyaniline-coated graphene nano-composites can be expected to improve the electrochemical properties of SnO2 remarkably.
