| 中文摘要: |
| 层状双金属氢氧化物（LDHs）因其结构和组成的可调性、阴离子交换性等优异的物化性能，被作为腐蚀抑制剂的载体广泛应用于金属材料的防腐蚀领域。归纳总结了目前LDHs最普遍的制备方法，包括共沉淀法、水热合成法、原位生长法、旋转涂膜法以及焙烧还原法等及其优缺点。同时从LDHs材料的耐蚀机制出发，阐述了LDHs薄膜与LDHs作为填料对金属基底保护的层间阴离子交换机制，以及掺杂稀土离子、羧酸盐抑制剂、石墨烯及其衍生物、环氧富锌涂层等与LDHs的复合协同增强耐蚀机制。通过表面预处理以及化学改性制备疏水性表面可以增强耐蚀性能，分析了LDHs材料在制备与工作过程中存在的问题：LDHs制备技术不够完善，LDHs薄膜与金属基底的结合力弱，LDHs薄膜的机械性能较差，LDHs与有机聚合物难以均匀混溶等。最后展望了LDHs材料在耐蚀领域的发展方向。 |

| Due to excellent physicochemical properties such as the anion exchangeability and the adjustability of structure and composition, layered double hydroxides (LDHs) are widely applied in the corrosion protection of metal materials as carriers for corrosion inhibitors. The most common preparation methods and corresponding advantages and disadvantages of LDHs were summarized, including coprecipitation method, hydrothermal synthesis method, in situ growth method, steam coating method and calcination reduction method, and the interlayer anion exchange system with LDHs film and LDHs as a filler to protect the metal substrate from the corrosion resistance mechanism of LDHs materials was also studied and the compound synergistic effect of rare earth ions, carboxylate inhibitors, graphene and its derivatives, epoxy zinc-rich coating and LDHs could also the corrosion re-sistance mechanism, Surface treatment and chemical modification were carried out to prepare a hydrophobic surface to enhance corrosion resistance, the problems in the preparation and working process of LDHs materials were analyzed: the preparation tech-nology of LDHs was not perfect, the bonding strength between LDHs films and metal substrates was weak, the mechanical prop-erties of LDHs films were poor, and the LDHs and organic polymers were difficult to be uniformly mixed. Through the above summary analysis, the development direction of LDHs materials in the field of corrosion resistance is prospected. |
