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 (CNT@PDA) 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.
成功地在 304 不锈钢（304ss）上涂覆了含有多壁碳纳米管（MWCNTs）的纳米杂化膜，以用于防腐。该纳米复合材料是通过贻贝启发的方法，通过聚多巴胺（PDA）的自组装，将 MWCNTs（CNT@PDA）包裹起来制成的。为了增强防腐性能，通过浸涂工艺构建了内层的 L-半胱氨酸，L-半胱氨酸通过巯基（-SH）官能团与 304ss 表面的粘性氨基酸。动电位极化测量和电化学阻抗谱表明，双层纳米层可以在 3.5%NaCl 中充当高贵的防腐涂层，这归因于疏水性、坚固性和致密的双层涂层。
