英文摘要	Novel super-hydrophobic aniline trimer-containing siliceous coatings were carefully acquired through electrodeposition in a mixed solution of tetraethoxysilane and triethoxysilylpropyl isocyanate modified aniline trimer (M-AT). Chemical constitution, morphology, hydrophobicity and anticorrosion ability of as-prepared hybrid coatings were investigated by corresponding equipment. Compared to pure silica coating, the AT-containing silica coatings presented excellent super-hydrophobicity and enhanced anticorrosion performance. The impedance was the highest and the corrosion current density was the lowest for modified silica coating with proper M-AT (5 wt%). The super-hydrophobic of AT-containing silica coating was conducive to avoid the direct contact between corrosion medium and metal substrate. The peculiar oxidation-reduction feature of AT was help to promote the generation of passivation films (ferric oxide and ferroferric oxide). The combined action of above-mentioned two functions facilitated the perfection of corrosion performance for AT-containing silica coating.
