摘要/Abstract

摘要： 从金属材料腐蚀特性及腐蚀保护要求出发，首先利用阳极氧化法制得ZnO薄膜，再通过恒电位法将ZnO薄膜用聚苯胺修饰得到ZnO/PANI复合薄膜。采用扫描电镜分析（SEM）、X射线衍射分析（XRD）、光电流、开路电位（OCP）及电化学阻抗等方法对制得的ZnO薄膜和ZnO/PANI复合薄膜进行物性分析和光电性能评价。研究表明：成功制得ZnO/PANI复合薄膜，且表现出优良的腐蚀保护性能。OCP实验表明，ZnO/PANI复合薄膜腐蚀保护性能与纳米ZnO薄膜相比提升了2～3倍。其中，光照后ZnO薄膜的光电流增加7μA，OCP下降5mV，复合薄膜的光电流增加22μA，OCP下降13mV。最后，失重实验对两种薄膜的光致阴极保护性能的分析数据显示，ZnO薄膜和ZnO/PANI复合薄膜都能对316L不锈钢和Q235碳钢起到光致阴极保护效果，但复合薄膜对316L不锈钢的保护效果尤为明显，其受腐蚀速率与在ZnO薄膜保护状态下相比降低了1倍以上。

Abstract: According to the corrosion characteristics and the corrosion protection requirements of metal materials, ZnO thin films were prepared by anodic oxidation method and then the ZnO films were modified by polyaniline by constant potential method. The properties of ZnO thin films and ZnO/PANI composite films were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), photocurrent, open-circuit potential (OCP) and electrochemical impedance spectroscopy (EIS). The results show that the ZnO/PANI composite films have been successfully prepared with excellent corrosion protection performance. The photocurrent and open-circuit potential (OCP) experiments show that the corrosion protection performance of the ZnO/PANI composite film is 2~3 times higher than that of the nano-ZnO thin films. The photocurrent of the ZnO thin film increases by 7μA, and the OCP decreases by 5mV, while the photocurrent of the composite film increases by 22μA, and the OCP decreases by 13mV. Finally, the analysis of the photo-cathodic protection performance of the two films shows that the ZnO thin films and the ZnO/PANI composite films both have photo-cathodic protection effect on 316L stainless steel and Q235 carbon steel. When we used the composite film to protect 316L stainless steel, the corrosion rate is less than half of that of the ZnO film.
