Nanohybrid films containing multiwalled carbon nanotubes (MWCNTs) were successfully coated on 304-stainless steel (304ss) for anti-corrosion use. The nanocompositewas made by a self-assembly of poly (dopamine), wrapped with MWCNTs ([email protected]) through a mussel inspired method. In order to enhance the corrosion protection, an inner layer of L-cysteine, an adhesive amino acid to 304ss surface through thiol (-SH) functional group were constructed through a dip-coating process. Potentiodynamic polarization measurements and electrochemical impedance spectroscopy revealed that the double nano-layer could act as a noble anticorrosive coating in 3.5% NaCl, which was assigned to the hydrophobicity, robustness, and dense double layer coating.

包含多壁碳纳米管（MWCNT）的纳米复合薄膜已成功地涂覆在304不锈钢（304ss）上以防腐蚀。由聚多巴胺的自组装制成的纳米复合材料，通过贻贝启发法包裹了多壁碳纳米管（[受电子邮件保护]）。为了增强防腐性能，通过浸涂法构建了L-半胱氨酸的内层，该内层是通过硫醇（-SH）官能团与304ss表面形成粘附性氨基酸。电位动力学极化测量和电化学阻抗谱分析表明，该双层纳米层可在3.5％NaCl中用作高贵的防腐涂层，这可归因于其疏水性，坚固性和致密双层涂层。
