Acrylonitrile–butadiene–styrene (ABS) is a commercial polymer for widely industrial applications due to its good mechanical and physical properties. However, there are only countable reports regarding its fibers from electrospinning. Comprehensive investigation on its optimized electrospinning parameters is missing. Herein, ABS fibers with different fiber diameters were produced by electrospinning. The electrospinning conditions, including the solvents, solution concentrations and amounts of different salt additives, have been comprehensively investigated. The morphologies of electrospun ABS fibers are studied by scanning electron microscopy and Raman spectroscopy. Different fiber diameters and coating densities are applied for filtration applications, which showed excellent filtration performance. The filtration efficiency of up to 99%, low pressure drop of < 30 Pa, and high filtration quality factor of up to 0.477 are achieved from the electrospun ABS fibers coated on microfibrous polypropylene substrates. In addition, the electrospun ABS fibers also shows good thermal stability and other applications such as oil/water separation.

ABS纳米纤维的电纺及其高过滤性能

丙烯腈-丁二烯-苯乙烯（ABS）具有良好的机械和物理性能，是一种广泛用于工业应用的商业聚合物。但是，仅有关于静电纺丝纤维的报道。缺少对其优化的电纺丝参数的综合研究。在此，通过电纺丝来制造纤维直径不同的ABS纤维。已经对电纺条件，包括溶剂，溶液浓度和不同盐添加剂的量进行了全面研究。通过扫描电子显微镜和拉曼光谱研究了电纺ABS纤维的形貌。不同的纤维直径和涂层密度适用于过滤应用，表现出出色的过滤性能。过滤效率高达99％，涂覆在微纤维聚丙烯基材上的电纺ABS纤维可实现<30 Pa的低压降和高达0.477的高过滤品质因数。此外，电纺ABS纤维还显示出良好的热稳定性和其他应用，例如油/水分离。
