Fumed silica and polydimethylsiloxane were mixed with water to prepare a suspension with a certain viscosity. The three-dimensional aggregates of fumed silica nanoparticles in the spraying process were used to form a micro-/nano-grade rough structure for super-hydrophobic coating, and a low surface energy material of polydimethylsiloxane was stored in the three-dimensional pores of gas-phase chain silica nanoparticles, and self-healing superhydrophobic coatings were prepared via simple spraying on the surface of different substrates. After the surface of the coating is destroyed by oxygen plasma, the coating can be restored to its super-hydrophobic performance by only placing at room temperature or treating at 100℃ for 30 min. The number of self-healing exceeds 20 times. Also, the coating has good high-temperature resistance, acid and alkali resistance, friction resistance and erosion resistance performance.
