利用烷基磷酸、金属锆离子和不锈钢电极表面的相互作用,通过表面自组装,在304不锈钢电极表面分别修饰了单层和双层烷基磷酸自组装膜,采用接触角和极化曲线对修饰电极进行测量.实验表明,双层烷基磷酸修饰膜具有更佳的耐腐蚀性能.

According to the complex interaction between dodecyl phosphonate and stainless steel surface as well as the zirconium ion,the self-assembled monolayer and double-layer dodecyl phosphonate modified 304 type stainless steel electrode were prepared.The electrodes were characteristiced by static contact angles and electrochemical polarization methods.The results suggested that the double-layer modified stainless steel electrode had better corrosion inhibition effect than the monolayer modified electrode.
