摘要/Abstract

摘要： 以聚丙烯腈(PAN)为鞘层,聚甲基丙烯酸甲酯(PMMA)为芯层,氧化锌(ZnO)为造孔剂,采用同轴静电纺丝技术制备出PAN复合纤维,经过煅烧、酸处理后制得中空多孔碳纳米纤维.采用透射电镜(TEM)对中空多孔碳纳米纤维的形貌进行表征,并考察了不同溶液浓度、电压、流速对中空多孔碳纳米纤维内外直径影响.结果表明:当内层溶液PMMA质量分数为10%,外层溶液PAN质量分数为10%,醋酸锌质量分数为6%,电压为15 kV,内、外层流速分别为1.0 mL/h和1.5 mL/h时,中空多孔碳纳米纤维的内外直径及介孔形貌最佳.

关键词: 同轴静电纺丝, 碳纳米纤维, 中空多孔, 氧化锌

Abstract: Core/shell polyacrylonitrile(PAN)fibers were prepared by coaxial electrospinning using PMMA solution as the core,PAN solution as the shell,ZnO as the pore former.After calcination and acid treatment,the hollow porous carbon nanofibers were obtained.Morphologies of the fibers were characterized by transmission electron microscope(TEM); and the effect of solution concentration,voltage and flow rates on core and shell diameters were also investigated.The results showed that the optimized condition for the satisfactory hollow porous carbon nanofibers was 10% PMMA,10% PAN,6% zinc acetate,15 kV,1.0 mL/h inner rate and 1.5 mL/h outer rates.

Key words: coaxial electrospinning, carbon nanofibers, hollow porous, zinc oxide
