This article is from Membranes, volume 4.AbstractIn this study, the polyvinylidene fluoride PVDF hollow fiber hemodialysis membranes were prepared by non-solvent induced phase separation NIPS. The influences of PVDF membrane thickness and polyethylene glycol PEG content on membrane morphologies, pore size, mechanical and permeable performance were investigated. It was found that membrane thickness and PEG content affected both the structure and performance of hollow fiber membranes. The tensile strength and rejection of bovine serum albumin BSA increased with increasing membrane thickness, while the Ultrafiltration flux UF flux of pure water was the opposite. The tensile strength, porosity and rejection of BSA increased with increasing PEG content within a certain range. Compared with commercial F60S membrane, the PVDF hollow fiber membrane showed higher mechanical and permeable performance. It was proven that PVDF material had better hydrophilicity and lower BSA adsorption, which was more suitable for hemodialysis. All the results indicate that PVDF hollow fiber membrane is promising as a hemodialysis membrane.
