摘要
静电纺丝是制备超细纤维和纳米纤维的新方法。静电纺丝能纺制直径在几十纳米至几微米之间的纤维并使其形成无纺布状的纤维毡。本实验在研制静电纺丝装置的基础上,以水溶性高聚物聚乙烯醇水溶液为纺丝液,制得直径在100nm~600nm的纤维。通过调节电压、纺丝液浓度及喷丝口与接收屏之间的距离等工艺参数得到不同粗细的纳米级纤维毡,研究了静电纺丝过程和工艺参数与纤维的表面形态特征之间的关系。研究结果表明,只有在一定的条件下,才能纺得稳定的和粗细均匀的纳米级纤维。
Electrospinning is a new method of producing super-fine fibers and nanofibers. It can spin fibers from nanometer to micrometer size in diameters and make them form fibrous membranes as nonwoven fabric. We used water-soluble polymer Polyvinyl alcohol(PVA)/H_2O solution to obtain fibers with diameters between 100nm and 600nm by electrospinning.Through changing the process parameters such as voltage、concentration of spinning solution and distance between capillary and collecting screen to fabricate different nanoscale fibrous membranes, relations between both electrospinning process and process parameters and morphology features of fibers were discussed. The results showed that the stable and even fibers could be spun on some condition.
