摘要
通过同轴静电纺丝技术，制备以胶原为壳层而PVA为核层的微纳米纤维，研究壳层胶原溶液的浓度和同轴静电纺丝工艺参数对PVA-胶原微纳米纤维形貌的影响。研究结果表明：壳层胶原溶液浓度越大，越容易获得串珠状PVA-胶原微纳米纤维；当纺丝电压为15～20kV，纺丝距离为15～20cm，壳层胶原溶液流速为0．1mL／h时，可以获得表面相对光滑的微纳米纤维。
In this paper, the PVA-collagen micro-nano fibers were prepared by coaxial electrospinning technique. The effects of collagen concentration and parameters of the coaxial electrospinning process on the morphology of PVA-collagen were investigated. Results show that the greater shell collagen concentration is, the more easily obtained beaded PVA-collagen micro-nano fibers;when the spinning voltage is 15～20 kV, the spinning distance is 15～20 cm, and the flow rate of shell collagen solution is 0. 1 mL/h, micro-nano fibers with relatively smooth surface can be obtained.
