石墨烯掺杂聚砜基正渗透膜的结构和性能
Structure and performance of forward osmosis membranes based on polysulfone substrates incorporated with graphene
摘要
Abstract
Polysulfone supporting layers incorporated with graphite(GI),graphene(GE),and graphene oxide(GO)were respectively prepared by phase inversion method. Then the polyamide active layers were preparedvia interfacial polymerization ofm-phenylenediamine and trimesoyl chloride on the supporting layers. The morphologies of top surface and cross section of the membranes were characterized by SEM. The porosity,hydrophilicity and performance of FO membranes with different incorporated additives were investigated. The results showed that the structures of the cross section of the supporting layers incorporated with GE or GO were looser,resulting in increased porosity and pure water permeability(PWP)constant. Thus the properties of corresponding FO membranes were improved. However,the incorporating of GI resulted in the prepared membrane with rough surface, dense cross section,lower PWP constant,and worse performance . The FO membrane prepared on the supporting layer incorporated with GO exhibited the best performance. The water flux reached 37.10L/(m2?h) under the AL-DS membrane orientation,increased by 38.7% compared with FO membrane prepared on pure polysulfone substrate.关键词
