Description

Technical Field

[0001] The utility model relates to the technical field of material surface modification, in particular to a metal material surface super-hydrophobic modification test box. Background Art

[0002] Superhydrophobic modification of material surface is one of the important ways to prepare superhydrophobic materials, which can generally be achieved by constructing a rough surface structure and modifying with low surface energy substances. The methods for modifying the surface of materials to be superhydrophobic include chemical etching and chemical deposition. Both methods can include four steps: surface reaction, water washing, alcohol washing and modification with low surface energy substances. The surface reaction in the chemical etching method is to use an acidic or alkaline etching solution for surface etching treatment, and the surface reaction in the chemical deposition method is to use a heterogeneous metal salt solution to deposit the metal material on the surface. After the surface reaction process, the rough surface structure of the metal material can be constructed.

[0003] In actual laboratory operations, both methods require the use of a large amount of chemical solutions, and each solution needs to be contained in a separate container, resulting in complex experimental equipment and extended process intervals. In addition, the etching solution / deposition solution is usually corrosive, and the organic modification solution is also volatile and toxic, which makes the experimental operation face cumbersome operating procedures and safety challenges.
