Regenerable adsorptive membranes prepared by mussel-inspired co-deposition for aqueous dye removal

In this work, we report on a regenerable and robust adsorptive membrane with superb dynamic adsorption capacity towards dyes prepared by a controllable mussel-inspired co-deposition of dopamine (DA) and polyethyleneimine (PEI) on a polyvinylidene fluoride (PVDF) microfiltration membrane. The DA oxidative self-polymerization occurred to form polydopamine for high adhesion with the PVDF membrane. On the other hand, the PEI provided a large number...
