两亲性高分子聚合物在膜表面物理改性中的应用

Application of amphiphilic macromolecular polymer in membrane surface physical modification

两亲性高分子聚合物由于在化学结构上的独特优势,在水处理膜表面物理改性中可以有效提高膜的通透性和耐污染能力。从膜的表面粗糙度、孔隙率等微观角度对两亲性高分子聚合物在膜表面物理改性方面的研究和应用做了综述。研究表明两亲性高分子聚合物无论是作为表面活性剂、表面涂层还是与原膜材料进行共混,都可以有效提高膜的渗透效率。

Due to the unique superiority of amphiphilic macromolecular polymer in chemical structure, it can effectively improve the permeability and anti-pollution capacity of the membrane when be used in membrane surface physical modification. The research and application of amphiphilic macromolecular polymer in membrane surface physical modification were summarized from surface roughness, porocity and some other micro aspects. The study showed that, no matter to be used as surfactant, surface coating or to be mixed with unmodified membrane, amphiphilic macromolecular copolymer could improve the membrane permeability effectively.
