摘要
通过多巴胺自发氧化聚合形成包裹的多壁碳纳米管(PDA@FMWCNT).利用聚多巴胺(PDA)的易附着能力,在铜(Cu)表面构造了基于PDA@FMWCNT的复合材料薄膜.利用拉曼(Raman)光谱、傅里叶变换红外光谱(FT-IR)、X射线光电子光谱(XPS)和扫描电子显微镜(SEM)对复合材料的结构进行了表征.利用电动位极化和电化学阻抗谱(EIS)法评价了PDA@FMWCNT在盐溶液中对金属的腐蚀保护性能.结果表明,PDA@FMWCNT复合涂层具有良好的防腐蚀性,并详细描述了其保护机理.
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.
