| Abstract: |
| Polydopamine(PDA) layers were wrapped over functionalized multi-walled carbon nanotubes(PDA@FMWCNT) by the spontaneous oxidative polymerization of dopamine. PDA@FMWCNT-based composites film was constructed at the surface of copper(Cu) by taking advantage of the easy attachment capability of PDA. The structure of composites material was characterized by Raman spectroscopy, Fourier transform infrared(FT-IR) spectroscopy, X-ray photoelectron spectroscopy(XPS), and scanning electron microscopy(SEM). The protection performance of PDA@FMWCNT for the metal in saline solution was evaluated using potentiodynamic polarization and electrochemical impedance spectroscopy(EIS). Consequently, PDA@FMWCNT composites film showed excellent corrosion inhibition and the protection mechanism was depicted in detail. |
