湿法纺丝工艺制备聚丙烯腈/氧化石墨烯复合纤维及性能研究
Research on the Preparation of Polyacrylonitrile/Graphene Oxide Composite Fiber and Its Properties Based on Wet-spinning Process
摘要
Abstract
By adopting polyacrylonitrile(PAN)and graphene oxide(GO),polyacrylonitrile/graphene oxide composite fibers with different contents of solid grapheme oxide were prepared by wet-spinning process.Based on nonsolvent induced phase separation theory,N-dimethyl formamide(DMF)/water mixture system was employed as coagulation bath,non-solvent(water)was diffused into PAN fibers and led to a quick PAN solidification.The morphology and structure of composite fibers were characterized via SEM and FTIR.The results of dynamic ther-momechanical analysis(DMA)indicated that when the solid content of GO reached 1wt.%,the composite fiber showed the best thermal mechanical property with storage modulus 5.5GPa and loss tangent 0.139.关键词
