| 摘 要： | 首次以二乙烯基苯为交联剂，在酸性催化剂的作用下对煤沥青进行了改性研究，同时对改性后的煤沥青进行显微结构和耐热性分析。研究结果表明：改性后的煤沥青不仅出现大量的中间相小球，而且耐热性优良，可作为炭材料优质的基体前驱体。

| Abstract: | Modification of coal tar pitch as a carbon precursor was studied using divinylbenzene (DVB) as a cross-linking agent by the aid of acid catalyst. The microstructure and thermostability of modified coal tar pitch had been studied. It was indicated that the modified coal pitch, which had not only a great deal of mesophase microbead but good thermostability as well, can be qualified to be an excellent carbon precursor. |
