摘要
聚偏氟乙烯的亲水改性方法主要有混合改性、表面移植改性、共聚改性和表面涂层改性等,由于不同改性方法对聚偏氟乙烯膜的亲水性、渗透性和抗污染性的影响效果不同,因此,探究一种效率高、经济成本较低、对提高抗污染能力具有较好效果的改性方法具有重要的现实意义。基于此,进一步展望亲水改性后的聚偏氟乙烯膜在工业应用方面的发展趋势。
The hydrophilic modification methods of polyvinylidene fluoride mainly include mixed modification, surface transplantation modification, copolymerization modification and surface coating modification. Because different modification methods have different effects on the hydrophilicity, permeability and anti-pollution of polyvinylidene fluoride membrane, it is of great practical significance to explore a modification method with high efficiency, low economic cost and good effect on improving the anti-pollution ability. Based on this, the development trend of hydrophilic modified PVDF membrane in industrial application is further prospected.
