以化学气相沉积法制备的纳米碳管粗产物和各向同性煤沥青为原料,采用热压成型工艺制备了纳米碳管/沥青复合材料,复合材料经1600℃高温热处理产物中生成了纤维状碳化硅(SiC)纳米线。扫描和透射电子显微分析表明所制备的SiC纳米线表面较为光洁,长度约为几个微米,直径约为30~80nm。二次电子像及其能谱分析表明原料中的金属镍颗粒和纳米碳管对SiC纳米线的生长具有重要作用。 Carbon nanotubes and bitumen composites were prepared by chemical vapor deposition and isotropic coal tar pitch. The carbon nanotubes / bitumen composites were prepared by hot press forming. Carbon fiber Silicon (SiC) nanowires. Scanning and transmission electron microscopy analysis showed that the surface of the prepared SiC nanowires is relatively smooth and has a length of about several micrometers and a diameter of about 30-80 nm. Secondary electron image and its energy spectrum analysis show that the metal nickel particles and carbon nanotubes in the raw materials play an important role in the growth of SiC nanowires.
