不同形状中间相沥青炭纤维的横断面结构 李明伟1,稻垣道夫2,王成扬1,郭崇涛1 (1.天津大学;2.日本国北海道大学) 摘要:在场发射扫描电子显微镜(FE-SEM)下观察了圆形,中空,条形和Y-形中间相沥青炭纤维的横断面结构.用流变学理论分析了纺丝过程中几种炭纤维结构的形成.提出中空纤维纺制时沥青流体的最大流速线在喷丝孔中心线的内侧,并根据中空炭纤维横断面的显微照片对此加以证实用催化缩聚中间相沥青制备的条形炭纤维显示出的特殊弧形对称结构,起因于中间相沥青的流变性质和条形喷丝孔的形状设计.非圆形中间相沥青炭纤维趋向于以线形为中心的放射状横断面结构,因而在热处理过程中能避免应力集中和裂纹产生,有利于提高炭纤维的抗压强度. 关键词:中间相沥青; 炭纤维; 结构; mesophase pitch; carbon fibers; texture; [全文内容正在添加中] ......
印刻法制备中间相沥青基中孔炭 詹亮1,梁晓怿1,张睿1,凌立成1,乔文明1,刘颖1 (1.华东理工大学,化学反应工程联合国家重点实验室,上海,200237) 摘要:用中间相沥青作碳源,硅胶水溶液作造孔剂,采用胶体印刻法制得一系列中孔碳.实验发现当适量纳米级硅源添加到中间相沥青中,会在彼此颗粒间形成一定的纳米孔道,从而导致中间相沥青在炭化过程中没有沥青由固相向液相转化的过程.结果表明:碳硅比,印刻温度以及中间相沥青的基本物化性质都将对中孔碳的孔结构发生重要影响.且制得比表面积和孔容分别为482m2/g和1.62cm3/g的中孔碳. 关键词:中孔碳; 印刻; 中间相沥青; Mesoporous carbon; Imprint; Mesophase pitch; [全文内容正在添加中] ......
