摘要
Abstract
Halloysite nanotubes(HNTs)were employed as functionally modified fillers,with hyaluronic acid(HA)grafted onto their surfaces to obtain HA-HNTs exhibiting enhanced hydrophilic properties.These modified HA-HNTs were blended with a polyacrylonitrile(PAN)solution and fabricated into mixed matrix membranes with varying HA-HNTs loading levels via a nonsolvent-induced phase separation method,followed by alkaline treatment.The structural and morphological characteristics of the HNTs before and after modification and the resulting mixed matrix membranes were systematically analyzed.Membrane performance was evaluated through permeability,retention,and antifouling tests using pure water,methylene blue solution,and bovine serum albumin solution.The results show that the HA-HNTs/PAN mixed matrix membrane prepared with 0.60 g of HA-HNTs demonstrate optimal comprehensive performance.The contact angle decreased from 61.49°(pure PAN membrane)to 56.64° after HA-HNTs incorporation,and further reduced to 45.64° post-alkaline treatment.The membrane exhibited a pure water flux of 143.16 L/(m2·h),a methylene blue retention rate of 99.77%,and a fouling rate of only 1.0%.The HA-HNTs-modified PAN membrane showcases superior hydrophilicity,retention capacity,and antifouling properties,which effectively prolong operational lifespan and reduce membrane replacement frequency in practical applications.关键词
