Abstract：

Plasma and ethanol pretreatment methods were used, respectively,to improve thedeposition of polydopamine(PDA) on the surface and in the pores ofpolypropylene microfiltration membrane. Detail comparison was made between the two methods through deposited density, membrane morphology and pure water flux. Results of deposition density and water permeation show that the ethanol pretreatment method is better than the plasma one in improving the deposition behavior of PDA for this kind ofmembrane. ATR/FT-IR, XPS and FESEM analyses confirm that after ethanol pretreatment, PDA can modify the membranes much more efficiently. EDX resultindicates PDA is uniformly distributed throughout the membrane. The performance of the modified membranes can last stable as long as 27 days. What’s more, the antifouling property can also be improved after PDA modification, revealed by the results of dynamic protein filtration experiments.
