摘　　要：为有效改善聚苯硫醚(PPS)织物亲水性不佳的问题,扩展其在碱性水电解池领域的应用,首先采用不同浓度硝酸对PPS进行改性,制备了HNO_(3)-PPS织物。并采用等离子刻蚀技术进一步改性,制备了HNO3/n-PPS织物。同时对织物的亲水性能、表面形貌、内部化学官能团、力学性能、透气性能以及电化学工作站效率进行表征分析。结果表明:当硝酸与水比例达到1.5∶1,等离子体放电功率达到80W时,织物亲水效果达到最佳。此时水接触角低至61.2°,织物水通量高达1730.1L/m^(2)·h。织物力学性能几乎不变,且电化学效率比未处理织物显著增加近3.5倍。提出的简单高效改性PPS织物方法,为其更好地应用于电解池提供了新的思路。In order to effectively improve the poor hydrophilicity of polyphenylene sulfide(PPS)fabric,the application of polyphenylene sulfide fabrics in the field of alkaline water electrolysis cells was extended.HNO3-PPS fabrics were prepared through hydrophilic modification of PPS using varying concentrations of nitric acid.Additionally,HNO_(3)/n-PPS fabrics were produced through further hydrophilic modification using plasma etching technology.The fabrics were analyzed for their hydrophilic properties,surface morphology,internal chemical functional groups,mechanics,air permeability and electrochemical workstation efficiency.The best hydrophilic effect of the fabric was achieved when the ratio of nitric acid to water was 1.5∶1 and the plasma discharge power was 80 W.The current water contact angle is 61.2°,with a fabric water flux of 1730.1 L/m^(2)·h.The mechanical properties of the fabric remain nearly unchanged,while the electrochemical efficiency has been significantly enhanced by nearly 3.5 times compared to the untreated fabric.Offers a novel perspective for its more effective application in the electrolytic cell.
