Abstract: |
|
Dopamine is a kind of biological neurotransmitter. In aqueous solution, it can be oxidized by dissolved oxygen and undergoes an oxidation-crosslinking reaction, forming a composite layer of polydopamine that strongly attaches to a substrate. Based on the characteristics of dopamine, in recent years, membrane technology researchers have performed surface modification via the self-polymerization-composite of dopamine on solid basement-membranes. Besides, the polydopamine composite layer with high reactivity offers a platform for further surface modification and functionalization. In this paper, research progress on modification and functionalization of membrane surface using dopamine was reviewed, the application fields included ultra/micro filtration, biomedical membranes and pervaporation film, etc. |
