Superhydrophobic coating, method for preparing same and use thereof

A superhydrophobic coating comprising:

• a three-dimensional porous nanocomposite structure, wherein the three-dimensional porous nanocomposite structure comprises a constructing unit and a bonding unit;
• wherein 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, wherein a surface of each of the hydrophobic polymer nanomicrospheres is wrapped by a plurality of the inorganic hydrophobic nanoparticles, wherein the hydrophobic polymer nanomicrospheres comprise an element selected from a group consisting of:
• polystyrene microspheres, organosilicon microspheres and polymethyl methacrylate microspheres, and wherein a ratio of a particle size of the inorganic hydrophobic nanoparticles to a particle size of the hydrophobic polymer nanomicrospheres is between 1:1 and 1:2.
