摘要
以粉末状聚丙烯腈溶解在二甲基甲酰胺溶液并在75℃水浴磁力搅拌制得前驱体溶液,采用静电纺丝法制备PAN/DMF复合纤维,运用溶胶-凝胶法浸渍氧化锌溶胶得到负载氧化锌的PAN/DMF纤维;将二水乙酸锌粉末按照不同质量分数比例溶解在二甲基甲酰胺溶液中,加入聚丙烯腈粉末加热磁力搅拌制备前驱体溶液,利用静电纺丝法制备负载乙酸锌的PAN/DMF纤维。将2种不同方法制备的纤维置于真空浮子流量计管式炉中进行270℃预氧化,并分别在650℃、800℃、950℃炭化制得负载氧化锌的活性炭复合纳米纤维材料,利用扫描电子显微镜对其微观形态进行观察,直接静电纺丝制备纤维效果要优于凝胶法制备纤维。
The precursor solution was prepared the powder dissolved in polyacrylonitrile solution two methyl formamide and in 75 ℃ water bath magnetic stirring, and PAN/DMF composite fibers were prepared by electrospinning method, and then Zinc Oxide Zinc Oxide PAN/DMF load fiber was prepared via sol-gel sol method;two water acetic acid zinc powder with different mass fraction of dissolved in solution two dimethylformamide, adding polyacrylonitrile powder heating magnetic preparation of precursor solution was prepared by mixing, supported zinc acetate by electrospinning PAN/DMF fiber.The fiber was arranged in the vacuum float flowmeter two different preparation methods of the tube is 270 ℃ preoxidation furnace, and separately prepared activated carbon loaded composite nano fiber material of Zinc Oxide at 650 ℃, 800 ℃ and 950 ℃ of carbonization and its morphology were observed by scanning electron microscopy, direct electrospinning the effect of fiber fiber preparation is better than gel method.
