摘　　要：以聚碳硅烷(PCS)为先驱体,经过高温裂解、化学气相沉积(CVD)过程,制备了SiC/多层石墨烯纳米复合材料。采用热差分析(TG-DTA)研究了PCS裂解过程。采用扫描电镜SEM、透射电镜TEM、拉曼光谱RAMAN以及X-射线衍射XRD等方法对纳米复合材料的形貌、结构进行表征分析。结果表明,合成出具有核心/壳层结构的纳米复合材料,核心为SiC颗粒(3C-SiC),壳层为多层石墨烯(~10层)组成的纳米石墨。The SiC/multilayer graphene nanocomposites were prepared from the Polycarbosilane( PCS) through high temperature chemical vapor deposition. The TG-DTA,scanning electron microscopy( SEM),transmission electron microscopy( TEM),Raman spectroscopy( RAMAN) and X-ray diffraction( XRD) and other test methods were used to characterize the morphology and the structure of the deposited nanocomposites prepared at different temperatures. The results show that the nano-composite material synthesized by this method has a shell / core structure with the core of the SiC particles(3C-SiC) and the shell of multi-graphene( ~10layers).
