摘　　要：以来源丰富、价廉易得的煤系沥青为原料,通过空气氧化法制备高软化点沥青,再进行溶剂萃取调制沥青族组成来制备适宜的发泡前驱体,采用自发泡法制备泡沫炭,利用偏光显微镜和扫描电镜观察其微观结构。结果表明,通过调制沥青的族组成可有效调控泡沫炭的孔貌结构,其中甲苯可溶物TS影响最为显著。As a new type of reticular functional carbon materials, carbon foam has broad application prospects. In this paper, the coal-tar pitch which has rich resource and inexpensive price in China was chosen to firstly modulate into high softening point pitch,then to prepare the proper precursor by solvent extraction. The carbon foams were prepared from the precursor obtained by self-foaming method. The microstructure of the carbon foams was observed by polarizing microscope and scanning electron microscope.The results show that the pore morphology of the carbon foam can be effectively controlled by modulating the composition of the pitch, among which toluene soluble has the most significant effect.
