Amine functionalized polysulfone (PSf) based ultrafiltration (UF) membranes were prepared by non-solvent induction phase separation method (NIPS) with reactive PSf (matrix) and polyehtyleneimine (PEI) (additive), where PEI was reacted in dope solution to give surface modified PSf-UF membrane. Unreacted PEI might be worked as a forming agent during NIPS, however it was not much affected to the pore structures. Obtained membranes showed enhanced hydrophilic property on the membrane, which increased the water flux without loss of the rejection rate of PEO (100 K).
