Antifouling performance is one of the most important issues in polymer membrane surface engineering,fabrication of anti-fouling membrane for the development of membrane separation technology is of great important.The copper nanoparticles were immobilized on the mesoporous silica surface to prepare mSiO2-Cu nanocomposites and the polyethersulfone nanocomposite membrane was fabricated by incorporating the mSiO2-Cu nanoparticles.The influence of particles on the membrane structure,antifouling and separation performances were evaluated.The results indicated that the pure water flux of membrane with 2% of mSiO2-Cu can reach 185L/(m2·h),which was 1.9 times that of PES basement membrane.The composite membrane had good antifouling property to the protein.When applied to the actual river water treatment,the results showed that PES/mSiO2-Cu membrane had good TOC removal rate and stability.
