中文摘要 | Metal aluminum (Al) is being widely used in industry and can be easily corroded in severe conditions. Recently, dopamine has been demonstrated to be an effective adhesive molecular that can be attached to virtually all material surfaces to form stable polydopamine coating (PDAc), exhibiting promiprospects in many fields. In this work, to improve the anti-corrosion performance of Al sheet, a npolydopamine-based 3-layer organic coating has been constructed by a multi-step self-assembly tnique for the first time. In brief, a self-assembled monolayer of (3-mercaptopropyl)trimethoxysi(coded as MPTS-SAM) was firstly prepared for enhancing the adhesion between the PDAc and thsubstrate. Subsequently, a PDAc was assembled onto the Al substrate by a simple immersion intodopamine hydrochloride solution at a pH of 8.5. At last, a layer of tetradecanoyl chloride was graonto the PDAc surface through amidation, which could apparently slow down the water diffusion tointerface of PDAc and Al for its prominent hydrophobicity. Corrosion resistance of the synthesized cing in NaCl solutionwas evaluated by potentiodynamic polarization test and electrochemical impedspectroscopy (EIS) measurement, respectively. As results show, PDAc on bare Al can protect the strate from corrosion to a certain extent. Significantly, after being mediated by MPTS-SAM underland covered by tetradecanoyl chloride outer layer, the anti-corrosion capability of the coating has been improved markedly. |
