| 摘 要： | 综述了几种不同的碳源,如低碳烃(甲烷、丙烯、乙炔和苯等)、脱油沥青、煤沥青,采用化学气相沉积(CVD)法,按不同转化过程制备出气相生长炭纤维(VGCFs)的研究现状.主要研究了以煤沥青为碳源、二茂铁为催化剂,借助CVD法制备气相生长炭纤维.经场发射扫描电子显微镜(FESEM)、高分辨透射电子显微镜(HRTEM)、X-射线衍射(XRD)及拉曼散射(Raman)分析,结果表明:产物主要为高纯度的VGCFs,直径分布均匀,外径大约为100 nm,长度数微米,并初步探讨了煤沥青制备气相生长炭纤维的生长机理.

| Abstract: | The development of vapor-grown carbon fibers(VGCFs),which were synthesized by chemical vapor deposition method using low carbon hydrocarbon(methane,propylene,acetylene,benzene),deoiled asphalt and coal pitch as carbon sources,were reviewed.Preparation of VGCFs by CVD from coal pitch with ferrocene as catalyst precursor was mainly studied.The products were characterized by field emission scanning electron microscopy(FE-SEM),high resolution transmission electron microscopy(HRTEM),X-ray diffraction(XRD)and Raman spectrum.Results showed that the products mainly consist of pure and straight VGCFs with diameters of about 100 nm and length of several micrometers.The growth mechanism of VGCFs was also discussed. |
