Effect of Functional Groups on Protein Adsorption Performance of Membrane Adsorbers

Functional groups on support membranes are important for the preparation of high-performance membrane adsorbers (MAs). In this work, effects different functional adsorption performance MAs were studied through surface modifications such as alkali treatment, oxidation treatment and polydopamine (PDA) deposition. Our experiment results indicate that chemical bonds prone to form between C-F PVDF amine PEI, which serves improve protein capacity. Furthermore, PDA deposition has potential enhance Introducing a layer with uniform pore size distribution shows
