Super-hydrophobic coating as well as preparation method and application thereof

The invention belongs to the technical field of functional materials, and particularly relates to a super-hydrophobic coating as well as a preparation method and application thereof. The super-hydrophobic coating is of a three-dimensional porous nano composite structure. The three-dimensional porous nano composite structure comprises a construction unit and a bonding unit, wherein the construction unit is formed by inorganic hydrophobic nanoparticles; the bonding unit is formed by hydrophobic polymer nano microspheres; and the inorganic hydrophobic nano-particles and the hydrophobic polymer nano-microspheres are mutually connected to form uniform pores. The durable super-hydrophobic coating of a novel composite structure is researched and designed from the essence of the super-hydrophobic coating, the durable super-hydrophobic coating is not limited by a spraying process and can be treated through a dip-coating or roll-coating process, coating of coiled materials and special-shaped parts can be achieved, the
