Problems solved by technology

[0005] In addition, there are sol-gel methods, template methods, and chemical deposition methods to prepare superhydrophobic surfaces of metal substrates, but most of the hydrophobic membranes are complex in process and their hydrophobic performance is not high, which is not conducive to wide application in industry.

Abstract

The invention relates to a method for depositing a superhydrophobic film on the surface of an aluminum substrate by using a soap solution. The steps of the method are as follows: grinding the aluminum substrate, removing oil stains and oxides on the surface of the aluminum substrate until the surface is smooth; using the treated clean and smooth aluminum plate as the cathode, and the titanium plate as the anode, in an electrolytic solution containing sodium dodecylbenzenesulfonate and soap After the corresponding time of electrodeposition in the middle, after drying in a drying oven, a super-hydrophobic film was obtained. The invention has the characteristics of simple process, low cost, good hydrophobicity and the like.

Description

Technical field: [0001] The invention belongs to the technical field of metal surface treatment, and in particular relates to a method for depositing a superhydrophobic film on the surface of an aluminum substrate by using an aqueous soap solution. Background technique: [0002] Aluminum alloy is widely used in civil industry, but its surface is easily corroded, which restricts its development, application and promotion. Therefore, it is very necessary to improve the corrosion resistance of aluminum substrate surface. [0003] A superhydrophobic surface generally refers to a surface with a contact angle with water greater than 150° and a rolling angle less than 10°. The preparation of superhydrophobic surfaces on metals is generally divided into two steps: first, a rough micro-nano structure is prepared on the metal surface, and then a layer of low surface energy substances is modified on the rough micro-nano structure. According to the Cassie-Baxter model, the contact of a...
