摘要
将维生素(VC)溶解在质量分数8%的聚乙烯醇(PVA)水溶液中,通过静电纺丝制得PVA/VC共混纳米纤维。分析了VC含量对溶液性能及静电纺丝速度的影响;测试了纤维的形貌结构及力学性能。结果表明:PVA/VC共混溶液属于切力变稀流体;当PVA/VC质量比为100/10或100/20时,共混溶液的电导率和静电纺丝速度较纯PVA溶液明显提高,制得的纳米纤维表面光滑,粗细均匀;与纯PVA纳米纤维比较,其平均直径和拉伸强度降低,断裂伸长率提高。
A polyvinyl alcohol/vitamin （PVC/VC） blend nanofiber was prepared by dissolving VC in 8% PVA solution by mass fraction via electrospinning process. The effect of VC content on the solution property and electrospinning velocity was analyzed. The morphology, structure and mechanical properties of the fiber were measured. The results showed that PVC/VC blend solution belonged to shear thinning fluid. As compared with pure PVA solution, the conductivity and electrospinning velocity of the blend solution were obviously increased when the mass ratio of PVA and VC was 100/10 or 100/20. The obtained nanofiber with smooth surface and even thickness showed the lower average diameter and tensile strength and higher elongation at break than pure PVA nanofiber.
