The film is superhydrophobic (the contact angle of water to the film in air is greater than 150°) and has a low adhesion to water of less than 5 microboules in air. The adhesion of water to water is measured using a high-sensitivity microelectromechanical balancing system (DataPhysics, DCAT 11 Germany). The 3 microliter-sized water droplets were fixed with a metal cap and controlled in an air atmosphere at a speed of 0.005 mms-1 to control the contact of the water droplets with the surface of the film, and then returned to the original position, and the change of the whole process force was recorded by a computer, and the film was read out. The adhesion of the surface to water droplets in the air.

The coating solution containing the polymer and inorganic colloidal crystal particles of the present invention is obtained by dissolving commercially available inorganic colloidal crystal particles and a polymer in a certain ratio in an organic solvent.

The sole of the invention having the anti-sludge splashing water does not need to be replaced with a new sole, and only the surface of the existing sole needs to be simply cleaned, and after drying, the coating solution containing the polymer and inorganic colloidal crystal particles is directly sprayed on the surface of the sole edge. After naturally drying, a film formed of a composite material of a polymer and an inorganic colloidal crystal particle is obtained on the surface of the edge of the sole to obtain a sole having a splash-proof water, thereby preventing the water from being carried when the person walks.
