摘要
采用高压静电纺丝技术制备了聚乙烯醇/壳聚糖(PVA/CS)的复合纳米纤维。通过扫描电子显微镜考察了纯聚乙烯醇PVA纤维和PVA/CS复合纳米纤维的形貌变化。研究表明,随着纺丝溶液浓度的不断增大,所得的纤维形貌越来越规则,纤维直径也逐渐变大。这种具有良好生物相容性的PVA/CS复合纳米纤维有望在生物医学方面得到应用。
Polyvinyl alcohol/chitosan （ PVA/CS ） hybrid nanofibers were prepared by electrospinning method. The morphology change of the pure PVA fibers and PVA/CS hybrid fibers was investigated via scanning electron microscopy. Studies have shown that with the increase of the concentration of eleetrospinning solution, the diameter of fibers became bigger, and the morphology of fibers became more regular. The PVA/CS composite nanofibers with good biocompatibility were expected to used in the field of biomedicin~
