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.
