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.
