Hydrophilic nanofiltration membranes with reduced humic acid fouling fabricated from copolymers designed by introducing carboxyl groups in the pendant benzene ring

Copolymers with high content of carboxyl groups designed by using BHPBA, BHPPE and DCDPS as monomers exhibited an improved thermal resistance without greatly sacrificing thermal stability and mechanical strength. Hydrophilic nanofiltration membranes fabricated from copolymers exhibited super high antifouling of humic acid, and high rejection of dyes and Na2SO4.204
