Abstract

The invention discloses a method for preparing a super-hydrophobic copper surface by combining electro-deposition with CVD. The method comprises the following steps: (1) copper sheet pre-treatment: sequentially placing a copper sheet into acetone solution, ethanol solution and deionized water solution, ultrasonically cleaning, and then mechanically polishing; (2) combining the copper sheet with a commercial anodic alumina template through a fixture, taking the copper sheet as a cathode, taking a platinum electrode as an anode, and taking nickel ion solution as an electrolyte for carrying out electro-deposition reaction; and (3) using small Parylene coating equipment for carrying out CVD chemical evaporation, so as to prepare the super-hydrophobic copper surface; and through a test, the obtained super-hydrophobic copper surface is excellent in super-hydrophobic performance, and capable of being used in the aspects of anti-fouling, anti-rusting and self-cleaning applications for a metallic copper surface. The method disclosed by the invention is simple to operate, short in processing time, and high in controllability.

Description

technical field [0001] The invention relates to a method for preparing a superhydrophobic surface, in particular to a method for preparing a superhydrophobic copper surface by combining electrodeposition and CVD. Background technique [0002] A surface with a contact angle greater than 150° and a sliding angle less than 10° is called a superhydrophobic surface. A typical example is the lotus leaf that "gets out of the mud without staining". Superhydrophobic surface has many excellent surface properties, such as self-cleaning, anti-corrosion, anti-icing and other properties, so it has broad application prospects in industrial production and people's daily life, such as self-cleaning clothes, anti-corrosion coatings, power transmission Line anti-icing and so on. [0003] Copper and its alloys have broad application prospects in industrial production due to their high storage capacity, high electrical conductivity, and high thermal conductivity. Failure due to chemical corros...
