The invention relates to the technical field of aircraft anti-icing and de-icing devices, in particular to an anti-icing and de-icing surface structure for aircraft skin, which comprises a base body, a working area is arranged on the base body, an ice dredging layer is arranged on the working area, and the ice dredging layer comprises a structural net and an elastic layer arranged on the surface of the structural net. Elastic filling bodies are arranged in meshes of the structural net, and the elastic modulus of the structural net is larger than the elastic modulus of the elastic layer and the elastic filling bodies. According to the anti-icing and de-icing surface structure, by means of elastic deformation differences, ice bodies directionally generate cracks on the structure net, and the de-bonding strength of the ice bodies on the anti-icing and de-icing surface structure is reduced; when the anti-icing and deicing surface structure is subjected to high-strength wind pressure, the pressure can be concentrated on the longitudinal ridges and the transverse ridges of the structural net, the upper pressure bearing limit of the anti-icing and deicing surface structure is improved, the safety and stability of the micro-nano structure are kept by the anti-icing and deicing surface structure under the high-strength wind pressure, and the aircraft can achieve the stable anti-icing and deicing effect in the extreme flight environment.
