Abstract

The invention discloses a system and method for preparing a bionic super-hydrophobic metal surface by laser-electrochemical deposition, and belongs to the field of bionic super-hydrophobic metal surface preparation. The method includes the following steps: (1) constructing a micron array structure on a metal substrate by a method of laser ablation and texturing; (2) removing nanoparticles and slag adhering to the surface of the micron structure during the ablation process by electrochemical polishing (3) The micro-nano composite structure is prepared by covering the surface of the micro-structure with densely distributed nano-pyramid structures by electrochemical deposition. Compared with the prior art, the method for preparing a superhydrophobic metal surface provided by the present invention does not require modification by low surface energy substances, the prepared metal surface also has good hydrophobic stability at low temperature, and can be applied to metal slopes, thus broadening the superhydrophobicity. Industrial applications of metal surfaces.

Description

technical field [0001] The invention belongs to the field of preparation of bionic super-hydrophobic metal surfaces, and relates to a system and method for preparing bionic super-hydrophobic metal surfaces by laser-electrochemical deposition. Background technique [0002] Represented by lotus leaves, the surfaces of many animals and plants in nature (such as water striders, floating leaves of Sophora figii, etc.) have super-hydrophobic properties. The static contact angle of water is greater than 150°, and the sliding angle is less than 10°. Water droplets can easily roll on its surface, so it has special properties such as waterproof and self-cleaning. Therefore, the preparation method of superhydrophobic surface based on biomimetic has attracted much attention. Laser ablation textured metal surface has the advantages of high precision, small thermal influence, good controllability, and less pollution, and has become one of the research hotspots; however, metals have high ...
