摘要

静电纺多孔珠状纤维在许多不同领域显示出巨大的工业应用潜力;此外,工艺参数对生产所需的多孔珠状纤维起着极其重要的作用。本研究采用静电纺丝法制备了聚苯乙烯多孔珠状纤维。为了进一步研究静电纺多孔珠状纤维的形成机理,系统、全面地研究了流速和外加电压对聚苯乙烯多孔珠状纤维射流运动和表面形貌的影响。利用高速摄影技术和扫描电镜技术分别拍摄了射流轨迹和纤维形态在选定参数下的图像,探讨了多孔珠状纤维的形成机理。实验结果表明,流量和施加电压对射流模式和纤维形貌都有较大的影响,即流量越大,形成多射流模式,珠粒直径越大;施加电压越大,形成多射流轨迹,珠粒数量和直径减小。

Preparation and Formation Mechanism of Electrospun Porous Beaded Fibers
Electrospun porous beaded fibers show great potential in the industrial application of many different fields; in addition, the processing parameters play an extremely important role in producing the required porous beaded fibers. In this study, polystyrene porous beaded fibers were fabricated via the electrospinning method. To further research into the formation mechanism of the electrospun porous beaded fiber, the influences of both flow rate and applied voltage on the jet motion and surface morphology of polystyrene porous beaded fibers were investigated in a systematic and comprehensive way. Images of jet trajectories and fiber morphologies under selected parameters were captured by high-speed photography and scanning electron microscopy, respectively, to explore the formation mechanism of porous beaded fibers. The experimental results showed that both flow rate and applied voltage have tremendous influence on the jet pattern and resultant fiber morphology, namely, the higher flow rate results in a multi-jet pattern and larger bead diameter, and the larger applied voltage leads to multi-jet trajectory and a reduction in the number and diameter of beads.
