Application of MXene/silane surface composite silane film in metal corrosion protection

The invention belongs to the field of metal corrosion protection, and particularly relates to application of an MXene/silane surface composite silane film in metal corrosion protection. The method comprises the following steps: preparing and hydrolyzing an MXene/silane mixed solution, carrying out surface treatment on a metal sample, dipping the metal sample in a mixed silane hydrolysate, and curing to form a film. The MXene/silane surface composite silane film protective surface treatment technology is adopted, the defect that a single silane film is not compact is overcome, the operation iseasy, safety and environmental protection are achieved, diffusion of a corrosive medium can be effectively hindered by doping the MXene, and the corrosion resistance of the silane film is improved. 本发明属于金属腐蚀防护领域，特别涉及一种MXene/硅烷表面复合硅烷膜在金属腐蚀防护中的应用。包括以下步骤：MXene/硅烷混合溶液的配置及水解，金属试样表面处理，金属试样在混合硅烷水解液中浸渍和固化成膜。本发明采用MXene/硅烷表面复合硅烷膜防护表面处理技术，解决了单一硅烷膜不致密的缺陷，且操作简单、安全环保，掺杂MXene能有效阻碍腐蚀介质的扩散，提高硅烷膜的耐腐蚀性能。
