摘要: 采用NaF刻蚀法和溶胶凝胶法合成了二氧化钛@二硫基噻二唑@二氧化硅(TiO2@DMTD@SiO2)纳米容器。利用X射线衍射(XRD)、傅里叶变换红外光谱仪(FTIR)、扫描电子显微镜(SEM)等对纳米容器的微观形貌和结构进行了表征,采用视频光学接触角测量仪测试了涂层的亲水性,并通过电化学测试了涂层的耐腐蚀性能。结果表明,掺杂TiO2纳米容器的环氧树脂涂层接触角最大,其接触角为71.9°,并且与空白涂层相比,在质量分数3% NaCl溶液中浸泡1~7 d后,具有更高的耐腐蚀性能。

Abstract: Titanium dioxide@2,5⁃Dimercapto⁃1,3,4⁃thiadiazole@silicon dioxide (TiO2@DMTD@SiO2) composite materials were synthesized by NaF hydrothermal etching combining with sol⁃gel method. The crystalline structures and morphologies were characterized by X⁃ray diffraction (XRD),Fourier transform infrared (FTIR) spectroscopy,scanning electron microscopy (SEM). The hydrophilicity of the coating was tested by the video optical contact angle, and the anticorrosion performance of the coating was evaluated by electrochemical method.The results show that contact angle of the epoxy coating with TiO2 doped nanocontainers is 71.9°,which can effectively prevent the invasion of corrosive media. Moreover, it has higher corrosion resistance than the blank epoxy coating, after immersing in 3% NaCl solution for 1 to 7 days.

Key words: TiO2, DMTD, Epoxy, Nanocontainers, NaCl solution
