Abstract With the extensive application of rubber products, more and more attention has been paid to rubber products with superhydrophobic properties. However, how to prepare superhydrophobic surface conveniently and on a large scale is of great significance to the application of rubber. In this work, a layer of silicon dioxide particles was sprayed on the surface of unvulcanized fluorosilicone rubber to construct the first-level microstructure. Then the structure of stainless steel woven net was successfully replicated on the surface of fluorosilicone rubber by template method, and the second hierarchical structure was constructed. The existence of functional groups, microstructure, hydrophobicity, droplet bounce and self-cleaning performance of the surface of the fluorosilicone rubber were analyzed. The results show that the multilevel microstructure prepared on the surface of fluorosilicone rubber by template method and spraying technology provide the supporting force and repelling effect for the droplets, and its static contact angle is (156.7±0.97)° and rolling angle is 1°. And the constructed multilevel structure surface had excellent droplet bouncing performance and good self-cleaning performance. Constructing multilevel structure on the surface of fluorosilicone rubber can greatly improve the hydrophobicity of the surface, which provided a new idea for preparing superhydrophobic surface.

Key words： multilevel structure spraying method template method fluorosilicone rubber superhydrophobic
