摘要： Bionic superhydrophobic coating has extremely broad application prospects and practical value. It is based on two important conditions, one is the construction of micro–nano structure, the other is the material with low surface energy. How to stabilize the micro–nano structure has become the focus of researches. In this work, a layer of Zn film is deposited on the stainless steel mesh with sturdy micron structure by RF magnetron sputtering. The solid micron structure of the stainless steel mesh itself, combined with the method of thermal oxidation, the surface of the stainless steel mesh is thus formed into a nanorod like ZnO nano structure, and then modified with perfluorodecyltriethoxysilane (PFDS) for low surface energy. The maximum contact angle of the superhydrophobic sample is 154.8°, and the minimum sliding angle is 2°, and it also has excellent corrosion resistance, thermal stability, self-cleaning, anti-aging and anti-icing properties, which provides a design idea for the preparation of superhydrophobic coatings.
