摘要:
采用同轴静电纺丝技术制备聚乳酸(PLA)-聚己内酯(PCL)核–壳结构复合纤维.利用扫描电子显微镜(SEM)观察纺丝电压、收集距离和核层-壳层溶液推进速度对PLA-PCL核–壳结构复合纤维形貌的影响.通过透射扫描电子显微镜(TEM)分析核层–壳层溶液推进速度对PLA-PCL核–壳结构形成的影响.研究结果表明:当核–壳溶液推进速度为0.1 -0.2和0.1 -0.3 mL/h时形成了清晰的核-壳结构;随着壳层溶液推进速度加快,PLA-PCL复合纤维核层含量降低,增加纺丝电压能够有效地降低复合纤维平均直径,而增大收集距离使复合纤维平均直径先降低后增加.
Abstract:
In this study,polylactic acid ( PLA )-polycaprolactone ( PCL) composite fiber with core-shell struc-ture was fabricated by means of co-axial electrospinning. SEM was employed to study the impacts of electro-spinning voltage,collected distance and ratio of core-shell solution injection speed on morphology of PLA-PCI.composite fiber with core-shell structure. The influences on the formation of the core-shell structure under dif-ferent ratio of core-shell solution injection speed were observed with TEM. The results showed that the obviouscore-shell structure was fabricated when core-shell solution injection speed was 0. 1-0.2 and 0.1-0.3 mL/h.The core component in PLA-PCL composite fiber decreases with the increase of shell solution injection speed.The increasing of electrospinning voltage could efficiently reduce the average diameter of composite fiber. Theaverage diameter of composite nanofiber decreases and then increases with the increase of collection distance.
