摘　　要：在聚苯乙烯(PS)溶液中添加十二烷基苯磺酸钠(SDBS)表面活性剂改变射流分裂行为,从而改善了电纺毡的结构与性能。利用高速摄像机、扫描电镜和万能拉伸机等研究了射流分裂过程、电纺毡的形态与力学性能。实验结果表明,SDBS使纺丝液的表面张力与电导率增加、黏度下降;射流的分裂点提前和纤维平均直径减小;纤维毡表面光泽性良好,均匀性提高,电纺毡力学性能明显提高。The properties of the polystyrene solutions and their splittings of the electrospinning jets were investigated with the surfactant sodium dodecylbenzene sulfonate（SDBS） added in the solutions.The high-speed camera,scanning electron microscope and universal tensile machine were used to examine the jet splittings,the morphology and the mechanical property of resultant mats.The results show that,the surface tension and electric conductivity of the solutions are increased whereas the viscosity is decreased in the presence of SDBS,and thus the splitting process is accelerated with the average diameter of the fibers being gradually reduced from 2.1 μm to 1.3 μm.Although the area densities of the electrospun mats are greatly decreased after addition of the surfactant,the uniformity and the mechanical property of the glossy mats are remarkably improved.
