摘要

Superhydrophobic biomimetic coating was achieved upon raw corroded steel surfaces by chemicalmodification. The in-situ textures of steel surfaces with different corroded conditions were utilized asthe microscale feature of the superhydrophobic biomimetic coating, and the hierarchical structures inthe form of perpendicular flake-like nanostructure formed by chemical modification as the nanoscaledfeature. The spectra of Fourier transform infrared-attenuated total reflectance showed the formedbiomimetic coating was chemically bonded with the steel surface for all samples. The average contactangles for the superhydrophobic biomimetic coating on slightly, moderately and seriously corrodedo o o steel surfaces were 149 , 161 and 158 , respectively. This superhydrophobic biomimetic coating canbe a basement of applying SH surface in the anticorrosion of pipelines in the future.
