Advanced anticorrosion coating materials prepared from fluoro-polyaniline-silica composites with synergistic effect of superhydrophobicity and redox catalytic capability

► SHS coating was prepared from SiO2 as roughness material and F-PANI as water repellent material. ► SHS coating have super-hydrophobicity properties and redox catalytic capability. ► SHS materials have good corrosion resistance and provide a barrier to aggressive species.
