以含有原生 QI的煤沥青为原料 ,采用热缩聚方法制备出中间相炭微球。用扫描电子显微镜 (SEM)观察了中间相炭微球的形貌和断面结构。经初步判断 ,在实验条件下原生 QI成核煤沥青基中间相炭微球更倾向于“地球仪”型结构。并对以 QI为核形成中间相微球的过程进行了分析。 Coal tar pitch containing primary QI was used as raw material to prepare mesocarbon microbeads by thermal polycondensation. The morphology and cross-sectional structure of mesocarbon microbeads were observed by scanning electron microscopy (SEM). After preliminary judgment, under the experimental conditions, primary QI nucleated coal tar pitch-based mesocarbon microbeads are more inclined to the “globe” type structure. The process of forming mesophase microspheres with QI as nucleus was also analyzed.
