  • 摘要: 为了研究低温等离子体对中空纤维膜的改性效果,对聚丙烯(PP)中空纤维膜进行了4种等离子体改性处理,以接枝率、力学性能、膜面官能团变化以及膜面形态为评价指标,比较了不同改性方法的改性效果。FT-IR特征分析发现,以同时照射法改性后的膜面官能团变化最大,且接枝率高,力学性能好。元素能谱分析表明,处理后的膜表面的N、O含量均有不同程度的变化,且与接枝率成正相关。SEM照片及力学性能反映出:改性后膜面存在损失,柔韧性变差。综合各指标的比较发现,同时照射法是一种最佳的改性方法。因此,特别考察了同时照射改性膜的清水通量的变化,结果表明,该方法能够大幅度提高膜的清水通量。
    Abstract: In order to study the effect of hollow fiber membrane modified by low temperature plasma, four plasma methods were applied in polypropylene(PP) hollow fiber membrane,seting graft yield, mechanical property, membrane surface functional group changes and membrane surface morphology as evaluation indexs,compared the four methods. FT-IR found that after modified by simultaneous irradiation method, besides membrane’s surface functional group had the greatest change, graft yield was high and mechanical property was well. Element energy spectrum analysis showed that the concent of nitrogen and oxygen in membrane surface also had different degree changes and it was positive correlation with graft yield after modification.SEM photograph and mechanical property reflected that the sueface of membrane existed wastage and the flexibility becomed poor. Comprehensive evaluation of every index discovered that simultaneous rradiation method was the best modification method of these four plasma methods. Consequently, simultaneous irradiation method was specially applied in modification membrane’s water flux change,the result showed that this method could improve the water flux of membrane largely.
