摘　　要：采用电纺法制备了壳聚糖／聚乙烯醇纳米纤维。考察了纺丝液配比和挤出速度对电纺纤维形貌的影响。结果表明：当壳聚糖质量比小于70％时，共混溶液的可纺性较好，纤维直径随着壳聚糖含量的增大而减小；随着挤出速度的增大，电纺纤维直径有逐渐增大趋势，挤出速度为0．5～0．8mL／h时得到的纤维形貌最佳。Chitosan/poly（vinyl alcohol） （CS/PVA） nanofibers were prepared by electrospinning. The effects of mass ratio of CS/PVA and flow rate of spinnable solution, were investigated. The results showed that, the solution was spinable when t the mass ratio of CS was less than 70 %, and the fiber diamter decreased as increasing the mas＇s ratio of CS; the fiber diameter increased as inceasing the flow rate, and the best fiber morphology was obtained at the flow rate of 0.5--0.8 mL/h.
