The invention belongs to the technical field of surface treatment, and relates to a nano superhydrophobic surface used for airplane antifreezing and deicing and a preparation method thereof. The preparation method comprises the following steps: making a hydrophobic microstructure on a substrate by non-silicon surface micromachining technology or microreplication method; coating a nano decorative film on the surface of the hydrophobic microstructure; and baking the prepared hydrophobic microstructure and the substrate coated with the nano decorative film to obtain the dry and clean superhydrophobic surface. The nano superhydrophobic surface improves the contact properties between the surface of an airplane and waterdrops and greatly reduces the degree that a fuselage is infiltrated by the waterdrops; and the nano decorative film can also further reduce the viscous force of the waterdrops when the waterdrops slip the surface of the fuselage, the number of the waterdrops condensed on the surface of the fuselage
