Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The preparation method of the superhydrophobic stainless steel mesh nano-aluminum film of the present embodiment comprises the following steps:

[0019] a. Grind the stainless steel mesh screen with sandpaper to remove the oxide layer on the surface, then put it into acetone, absolute ethanol and deionized water and clean it with ultrasonic vibration for 10 minutes to remove surface impurities; use it after ultrasonic vibration cleaning After washing with pure water, air-dry with a fan for subsequent use; the stainless steel mesh used in this embodiment is a 150-purpose stainless steel screen;

[0020] b. Weigh 0.1g of nano-aluminum powder and disperse it in 100ml of a mixed solution composed of ethanol and acetylacetone. The volume ratio of ethanol to acetylacetone is 1:1. After sealing with a plastic film, ultrasonically oscillate for 20 minute...

Abstract

The invention discloses a preparation method of a super-hydrophobic stainless steel mesh nano-aluminum thin film. The preparation method comprises the following steps: a, grinding a stainless steel mesh by using abrasive paper so as to remove an oxide layer on the surface, subsequently feeding the stainless steel mesh into acetone, absolute ethyl alcohol and deionized water in sequence, carrying out ultrasonic oscillation cleaning to remove impurities on the surface, and then carrying out air drying for later use; b, preparing stable suspension; (the intermediate steps are omitted); f, takingout the stainless steel mesh treated in the step e, then leaching with the absolute ethyl alcohol, and putting the stainless steel mesh into a drying oven for drying to obtain the super-hydrophobic stainless steel mesh nano-aluminum thin film. According to the preparation method of the super-hydrophobic stainless steel mesh nano-aluminum thin film, disclosed by the invention, a contact angle of the obtained super-hydrophobic stainless steel mesh nano-aluminum thin film is as high as 155 to 165 degrees, and a rolling angle is smaller than 10 degrees. In addition, in the preparation process of the super-hydrophobic stainless steel mesh nano-aluminum thin film, simple required equipment, efficient deposition, low cost and uniform film layer are realized; a large amount of precious metals, strong acid and strong base are avoided, so that the cost and the risk of preparation are reduced.

Description

technical field [0001] The invention relates to the technical field of micro-nano materials, in particular to a method for manufacturing a super-hydrophobic stainless steel mesh. Background technique [0002] Inspired by the "lotus leaf effect" and "rose effect", superhydrophobic surfaces have attracted great attention from researchers. These surfaces with special wettability (superhydrophobic, superoleophobic, superamphiphobic) have extremely important application prospects in many fields such as daily life and industry, such as self-cleaning, anti-icing, oil-water separation, anti-corrosion, etc. . A superhydrophobic surface refers to a surface with a contact angle with water greater than 150° and a rolling angle less than 10°. To achieve super-hydrophobic effect, the surface must have a rough surface microstructure and a low surface energy hydrophobic layer. So far, the preparation of superhydrophobic surfaces is still in the stage of exploration and development, and f...
