Abstract: Modification of a membrane surface is critical to help further functional protein binding on the membrane. Mussel inspired modification and metal chelating agent grafting on the polyvinylidene fluoride (PVDF) is proposed to increase the hydrophilicity, stability, and functionality of the membrane. This study carried out a four steps modification including polymerization of dopamine, grafting with poly (ethyleneimine) (PEI) and metal chelating agent and finally metal (ZnO) coupling. Characterization of the modified membrane was carried out using contact angle observation, permeate flux analysis, FT-IR spectrum and FESEM analysis. The results show a successful PDA and PEI deposition on PVDF membrane with significant improvement of the membrane hydrophilicity and wettability. Permeate flux analysis showed blockage on membrane surface due to the successful coating. Absorption peak increased slightly showing the deposition of PDA/PEI. Successful Zn2+ ion coupling can be seen clearly from the FESEM analysis
