摘要:

在钛酸正丁酯水解溶胶中加入二甲基酰胺 (DMF),通过浸渍-提拉法制备了TiO₂膜。应用XRD、Raman光谱、SEM和接触角测量等表征手段对比分析了无添加和添加DMF所制备TiO₂膜在组成、微观形貌以及表面润湿性等方面的特性,并结合光电化学技术研究了该体系在紫外光作用下的光响应特征和光生阴极保护能力。结果显示,DMF的添加有效提升了TiO₂膜的连续致密性,在光照作用下可对基体金属提供稳定的阴极保护,且表现出更加优异的暗态防护性能,有效阻止溶液中Cl^-在膜层中的传输。

关键词 ：光生阴极保护, 改性TiO₂, 不锈钢, DMF

Abstract：

TiO₂ film surface normally presents micro porous after annealing treatment, which is one of the key factors on restraining the application of photogenerated cathodic protection of it. This study has prepared DMF modified TiO₂ film by sol-gel and dip-coating method on the substrate of FTO glass. The influence of DMF on the corresponding film composition, microstructure and surface wettability are explored by XRD, Raman spectroscopy and SEM. The property of photo response and cathodic protection behavior of the film coupled with 316 stainless steel are studied under UV illumination. The results indicated that the addition of DMF has essentially improved the compact continuity of the TiO₂ film, which supplies effective inhibition on the corrosive ions migration to the substrate. And the modified film presents comparable photogenerated cathodic protection property to that of pure TiO₂ film.

Key words： photogenerated cathodic protection modified TiO₂ film stainless steel DMF
