摘要
采用静电纺丝技术制备壳聚糖/聚乙烯醇(CS/PVA)复合纤维,研究其材料配方和配制时间对溶液黏度、电导率和制备获得的CS/PVA复合纤维形态、直径分布及平均直径的影响.结果表明:壳聚糖的加入增加了CS/PVA混合溶液的黏度和电导率,且随着配制时间的增长,溶液的黏度发生明显下降.另外,随着CS组分含量的增加,制备获得的CS/PVA复合纤维平均直径明显降低,且直径分布均匀性增加;随着溶液配制时间的增长,CS/PVA混合溶液的成纤能力急剧下降.
Chitosan （CS）/poly （vinyl alcohol） （PVA） composite fibers were fabricated by electrospinning in this study. The influences of material formulation and formed time on the viscosity, electrical conductivity and the morphology, average diameter, diameter distribution of CS/PVA composite fiber were investigated. The re- suits showed that, the introduction of CS could increase the viscosity,electrical conductivity of CS/PVA blend solution. And the viscosity of blend solution decreased with the increase of formed time. In addition, the more CS content Was, the smaller diameter of CS/PVA composite fiber would be. The fiber-forming capacity of CS/ PVA blend solution decreased dramatically as the solution formed time increased.
