摘　　要：本研究采用溶胶-凝胶方法,成功地合成了涂覆在钢材表面具有优异防腐性能的超疏水硅烷/氧化石墨烯(SSi-GO)复合涂层。利用傅立叶变换衰减全反射红外光谱、拉曼光谱、接触角测试仪和扫描电子显微镜表征了所制备的SSi-GO涂层的结构和形貌,测试结果表明,硅烷和GO纳米片之间发生共价反应,形成了更具保护性和耐久性的涂层。采用盐雾实验和电化学方法研究了涂覆SSi-GO涂层钢材的耐腐蚀性能,实验结果表明,SSi-GO复合涂层有效地提升了钢材的耐腐蚀性能。This study successfully synthesized a superhydrophobic silane/graphene oxide(SSi-GO)composite coating with excellent corrosion protection performance on steel surfaces by sol-gel method.The structure and morphology of the prepared SSi-GO coating were characterized using Fourier transform infrared spectroscopy,Raman spectroscopy,contact angle goniometer,and scanning electron microscopy.The test results indicate that a more protective and durable coating is formed due to the covalent reaction between silane and GO nanosheets.The corrosion resistance of plate coated with the SSi-GO coating was investigated using salt spray experiments and electrochemical methods,demonstrating that the SSi-GO composite coating effectively enhances the corrosion resistance of plate.
