摘要	Bioinspired superhydrophobic surfaces (SHS) have potential application prospects in many fields, but weak mechanical stability of the microstructures has become the main bottleneck. In this work, the water-glass strengthened the interfacial force between the inorganic SiO2 and ZnO particles and the substrate through chemical reaction rather than physical embedding, which obtains a robust superhydrophobic surface. Based on surface characterization and analysis, the mechanism of the water-glass that played a role of enhancing the interface between the particles and the substrate in the coating was explored and proposed. Furthermore, the effect of the treatment temperature on the surface structure of the water-based paint during the spraying process was studied. Through simulating different environments, the anti-acid and -alkali resistance and anti-aging ability were tested in the full pH range or under strong UV irradiation, showing an excellent performance. Different mechanical stability tests confirmed that the silicate network structure enhances the binding force between the particles, improving the robustness of the superhydrophobic surface. This work may provide a new insight for the construction of superhydrophobic surfaces with enhanced interfaces.
