Abstract: |
Polydopamine (PDA) can attach to the surfaces of glass, stainless steel, plastic, rubber, politetrafluo-roethylene, and other materials because it contains abundant phenolic hydroxyl and amino functional groups. Therefore, PDA has currently become an important and popular material. In this study, the synthesis methods of PDA, polymerization mechanism of PDA and its adhesion, and application of PDA in the field of marine antifouling/anticorrosion in recent years are reviewed. This study provides a reference for researchers to the investigation status of PDA. |
