摘要:
为了得到亲水性和抗污染性能好的聚丙烯微孔膜，采用表面涂覆法将聚乙烯醇固定在聚丙烯膜的表面.通过红外光谱对聚丙烯微孔膜改性前后的基团进行了表征；研究了反应时间、聚乙烯醇浓度等反应条件对聚乙烯醇固定率的影响.结果表明，聚乙烯醇的固定率随着反应时间和聚乙烯醇浓度的增加而增加.最佳反应条件为50 ℃下反应2 h，聚乙烯醇质量分数为1%，戊二醛质量分数为2%，得到的改性膜的水接触角从110°下降至62°，两个月内水通量的变化不明显，膜的亲水性和抗污染性较好.
Abstract:
Surface modification of polypropylene microporous membrane was researched by dipcoating to immobilize polyvinyl alcohol on the surface for the purpose of getting high hydrophilic modification and antipollution.The structure was studied by flourier transform infrared spectroscopic.The effects of reaction time and concentration of polyvinyl alcohol on the immobilization degree of microporous membrane were studied.The results show that the immobilization degree of polyvinyl alcohol is improved with the increase of reaction time and concentration of polyvinyl alcohol; the optimum reactive conditions are polyvinyl alcohol of 1.0wt% and glutaraldehyde of 2.0wt% heating at 50 ℃ for 2 h;the water contact angle is decreased from 110° to 62° and the change of water flux in two months is not obvious.The microporous membrane has excellent hydrophilic modification and antifouling performance.
