摘要
以聚偏氟乙烯 (PVDF)和聚醋酸乙烯酯 (PVAc)共混 ,采用相转化法制备亲水性小截留分子量共混超滤膜 .本文对PVDF和PVAc共混前后超滤膜性能进行了比较 ,结果表明 。
The hydrophilic small molecular weight cut off(MWCO) blend ultrafiltration (UF) membranes are prepared from polyvinylidene fluoride(PVDF) and polyvinyl acetate(PVAc) by phase inversion method. A comparison of performances between PVDF UF membrane and blend UF membrane is carried out. The results indicate that the water flux of blend membrane is increased and the cost is decreased on the premise of same retention.
