摘要
为改善聚苯硫醚(PPS)织物的亲水性,采用介质阻挡放电等离子体引发苯乙烯磺酸钠(SSS)在PPS织物上接枝聚合.考察了低温等离子体放电功率、处理时间以及苯乙烯磺酸钠质量分数对接枝后PPS织物水通量的影响.利用响应面优化试验得到最佳接枝条件为等离子体放电功率5.2 W,处理时间122 s,乙烯磺酸钠质量分数12％,此条件下PPS织物水通量最大达到15 897.62 L/(m2·h),相比原织物提高了103.5％.通过扫描电子显微镜(SEM)、X射线光电子能谱(XPS)等方法对织物形貌和结构进行表征,结果表明,苯乙烯磺酸钠被成功接枝到PPS织物表面,对织物的水通量有较大改善,且改性织物经过5次清洗后仍能保持较好的性能.
Abstract
To improve the hydrophilicity of polyphenylene sulfide(PPS)fabric,sodium styrene sulfonate(SSS)was grafted onto PPS fabric using dielectric barrier discharge plasma initiation.The effects of low-temperature plasma discharge power,treatment time,and content of SSS on the water flux of grafted PPS fabrics were studied.The optimal grafting conditions obtained through response surface optimization experiments were as follows:plasma discharge power of 5.2 W,treatment time of 122 s,and SSS content of 12％.Under the conditions,the maximum water flux of PPS fabric reached 15 897.62 L/(m2·h),which was 103.5％higher than that of the original fabric.The morphology and structure of the fabric were characterized by scanning electron microscopy(SEM)and X ray photoelectron spectroscopy(XPS).The results showed that sodium styrene sulfonate were successfully grafted onto the surface of PPS fabric,which significantly improved the water flux of the fabric.The modified fabric still maintained good performance after 5 times of cleaning.
