摘要: A simple, scalable method for fabricating fouling-resistant ultrafiltration membranes is described. self-doped, sulfonated form of polyaniline was blended into polysulfone (PSf) (UF) to enhance hydrophilicity and fouling resistance. Polyaniline in its base with fuming sulfuric acid, yielding (SPANi) a degree sulfonation ∼0.5 confirmed by XPS. The SPANi polymer dedoped dissolved solution N-methylpyrollidone at varying concentrations. During phase inversion membranes, redoped precipitated within the PSf membrane films facile one-step process. Composite containing increasing amounts were compared pure determine changes performance, hydrophilicity, antifouling characteristics. composite exhibit fluxes similar those maintain rejection properties current UF mem...
