Here we presented an ultra water-repellent surface with the ternary composite structures, expecting to provide an inspiration to the application research. Our strategy is to design macro ridge structures on the superhydrophobic surface, which is prepared by modifying the composite micro-nanoscale hierarchical structures with FAS-17. The effect of micro-nanoscale hierarchical structures on the non-wettability were firstly analyzed arid examined for achieving a perfect unity of microstructures and property. On this basis, we designed the macro ridge structures and obtained the final sample surface, which could not only display a strong superhydrophobicity with the apparent contact angle reaching 161 and the contact angle hysteresis reducing to 1.5, but also exhibit the capacity to compel the impact water droplet to bounce off within an extreme short time (5.5 ms).
