摘要
传统熔体电纺的设置通常需要一个大型高压电源来提供电场而且需要外界的持续供电,受使用环境的制约[1,2]。本文中,我们利用一个手摇感应起电机作为供电电源制作了静电纺丝装置。使用此电源,一方面可以避免纺丝高压供电电源和加热系统供电电源之间地相互干扰;另一方面可以使静电纺丝脱离外界的持续供电,使设置非常方便和安全。利用此装置成功电纺了直径约15~45μm的聚乳酸(PLA)纤维。研究了手摇感应起电机手柄的旋转速度和电纺距离对纺丝效果的影响。此外,研究了PLA纤维直接沉积到猪肝上的温度和粘合度。结果表明,装置和电纺的聚合物纤维可用于伤口愈合敷料。
Conventional melt electrospinning setup usually needs a large high-voltage power supply, which limited by the using conditions. In this article, we report a new melt-electrospinning setup based on a small hand-operated Wimshurst generator, which can avoid electrical interference between the high-voltage spinning system and the heating system, and make the setup very portable. Poly(lactic acid)(PLA) fibers with diameters of 15–45 μm were successfully fabricated by using this apparatus. Experimental parameters such as the rotational speed of the generator handle and the spinning distance were investigated. In addition, PLA fibers were directly melt-electrospun onto a pork liver, and the temperature and adhesiveness of the deposited fibers were studied. The results indicate that the apparatus and melt-electrospun polymer microfibers can be used in dressing for wound healing.
