| 摘 要： | 利用原位聚合法成功制备了聚对苯撑苯并双噁唑(PBO)/单壁碳纳米管(SWNT)复合物,并用干喷湿纺法对聚合物进行了纺制.SWNT采用强氧化性酸处理,形成羧基化的单壁碳纳米管(SWNT-COOH).用拉曼光谱(Raman)、X射线光电子能谱(XPS)、强度测定、热重分析等分别对SWNT、PBO/SWNT复合纤维进行了表征.研究表明,碳纳米管经过酸处理后,表面含有较多的羟基和羧基官能团.PBO/SWNT复合纤维保持了PBO纤维的优异耐高温性能,纤维拉伸强度与同条件下PBO纤维相比提高了50%.

| Abstract: | PBO/SWNT composites were successfully synthesized by means of the in-stiu polymerization procss,and spun into fibers through the dry-jet wet spinning.The single-walled carbon nanotubes were treated with strong oxidizability acids to form the carboxylic single-walled carbon nanotubes.SWNT and PBO/SWNT fibers were analyzed by means of Raman spectroscopy and X-ray photoelectron spectroscopy respectively.The thermal resistance and the tensile strength of SWNT and PBO/SWNT were characterized.The results show tha... |
