Polydopamine

Forward osmosis is a rapidly emerging technology that has potential to enable low cost water treatment and desalination. Previous investigations have found that reverse osmosis (RO) membranes were unsuitable for forward osmosis in part due to their hydrophobic support layers, which inhibit wetting.

The fouling, in particular the organic fouling of anion exchange membranes (AEMs), is a serious problem in electrodialysis (ED). In this paper, we attempted to improve the antifouling potential of AEM by surface modification with polydopamine (PDA). The antifouling potential was evaluated by the tran
