Abstract: |
|
Dopamine (DOPA), as the typical biomimetic mussel material, has attracted much attention in the field of composite membrane preparation due to its simplicity, universality and good post functionalization potential in the process of membrane surface modification in recent years. Dopamine can generate polydopamine(PDA) through self-polymerization in weakly alkaline aqueous solution, but the self-polymerization is usually a slow process, and the rate of self-polymerization can be increased by adding oxidant. In this paper, the influence of oxidants addition(such as ammonium persulfate, sodium periodate and other oxidants) on dopamine polymerization process, PDA stability and antifouling performance of the composite membrane is mainly reviewed. Furthermore, membrane surface modification technology of dopamine polymerization in membrane biofilm reactor(MBfR) system is also discussed, the composite membrane obtained by dopamine polymerization modification is expected to obtain excellent oxygen mass transfer performance, biological affinity and antifouling properties, and has good application prospect in the field of MBfR. |
