Polyphenylene sulfide (PPS) nanofibers have broad application prospects in high temperature dust removal, high temperature oil‐water separation, radiation protection, and other fields. PPS nanofibers were prepared by melt differential electrospinning without any other additives, which ensures the excellent properties of PPS fibers. The effects of spinning parameters (spinning voltage, spinning distance, spinning temperature) on the morphology of PPS fibers were systematically studied, and the average diameter of PPS fibers with 1.28 μm was obtained under the optimum conditions (spinning distance of 6 mm, temperature of 310°C and spinning voltage of 35 kV). The effect of spinning voltage on the crystallinity and thermal stability of the fiber was analyzed. Finally, the filtration efficiencies of the commercial dust‐proof filter bags and the obtained PPS fibers with the same weight were compared. It was demonstrated that filtration efficiency of the obtained PPS fibers with 186 g/cm² reached up to 99.95%. This study aims to provide a new idea for green industrial manufacturing and application of electrospinning PPS nanofibers.

烟气过滤用聚苯硫醚纳米纤维的熔体差分静电纺丝

聚苯硫醚（PPS）纳米纤维在高温除尘，高温油水分离，辐射防护等领域具有广阔的应用前景。PPS纳米纤维是通过熔融差分静电纺丝法制备的，不含任何其他添加剂，从而确保了PPS纤维的优异性能。系统研究了纺丝参数（纺丝电压，纺丝距离，纺丝温度）对PPS纤维形态的影响，在最佳条件下（纺丝距离为6mm，温度为25℃），获得了1.28μm的PPS纤维平均直径。 310°C和35 kV的旋转电压）。分析了纺丝电压对纤维结晶度和热稳定性的影响。最后，比较了商用防尘滤袋和获得的相同重量的PPS纤维的过滤效率。结果表明，所获得的PPS纤维的过滤效率为186g / cm²达到99.95％。这项研究旨在为绿色工业制造和静电纺丝PPS纳米纤维的应用提供一个新思路。
