Abstract
A superhydrophobic coating having a three-dimensional porous nanocomposite structure, includes: a constructing unit and a bonding unit; the constructing unit comprises inorganic hydrophobic nanoparticles, the bonding unit comprises hydrophobic polymer nanomicrospheres, and the inorganic hydrophobic nanoparticles and the hydrophobic polymer nanomicrospheres are interconnected to form uniform pores. A method for preparation of the superhydrophobic coating includes: mixing the inorganic hydrophobic nanoparticles with the hydrophobic polymer nanomicrospheres in a dispersant to form a coating solution; and coating the coating solution on the surface of a substrate using a dip coating, roll coating or spray coating process, and drying to form the superhydrophobic coating of a three-dimensional porous nanocomposite structure.
