According to the super-hydrophobic surface capable of preventing the air conditioner from frosting and the preparation method of the super-hydrophobic surface, the material surface with a micro/nano composite structure is designed and prepared, the micro structure is subjected to hydrophilic treatment, and the material is applied to areas such as an air conditioner outdoor unit, so that the super-hydrophobic surface can repel supercooled water under the conditions of high supercooling degree and high humidity; the super-hydrophobic state is stably kept for a long time, and frost caused by condensation and freezing of supercooled water is prevented. Under the conditions of high supercooling degree and high humidity, due to the superhydrophobicity of the surface, the adhesion force of supercooled liquid drops on the surface is extremely low, and the supercooled liquid drops can be automatically separated under the action of gravity. The surface can be prepared on the surfaces of various materials, anti-frost su
