Surface Modification of Poly(ether imide) Support Membrane for Preparation of Anti-fouling Ultrafiltration Membrane
Abstract:
Asymmetric porous support membrane of Poly(ether imide) (PEI) was prepared by using immersion precipitation method from a casting solution of 15 wt% solution of PEI in N-methylpyrrolidone (NMP) and water used as non-solvent. The surface of PEI support was treated with 4 wt% of 2-aminethanole solution (AEOH). The effect of the reaction time on the morphology, hydrophilicity, pure water permeability, BSA rejection and mechanical properties of membrane were investigated. The chemical structure change during the modification process was monitored by FTIR-ATR, which indicated that hydrophilic functional groups such as hydroxyl and amide groups were generated on the PEI support. It was found that water permeability of modified PEI support membrane was relatively high compared to parent PEI membrane.
