Inspired by mussel’s adhesion, polydopamine surface chemistry have been investigated for the material-independent surface functionalization. So far, a variety of applications have been reported in energy, biomedical and environmental research fields. However, the practical applications of polydopamine in industry are hindered by the slow coating rate. Herein, we report that the coating kinetics of polydopamine and other polycatecholamine can be largely accelerated by microwave irradiation without an addition of any chemical oxidizing agent. Polydopamine nanofilm is formed in 15 min of coating time under the microwave irradiation, whereas it takes > 6 h to reach the same film thickness under the ambient condition. The observed acceleration is resulted from microwave-induced radical generation, which subsequently enables radical polymerization of dopamine. |
