A kind of preparation method of copper substrate superhydrophobic surface

Abstract

The invention discloses a manufacturing method of a copper substrate super-hydrophobic surface and belongs to the technical field of material surface machining. The manufacturing method of the copper substrate super-hydrophobic surface includes the steps that a micron-grade coarse structure is built on the surface of a copper substrate, and a first surface is obtained; hydroxylation treatment is conducted on the first surface, and a second surface is obtained; the copper substrate is placed into an organic solution, a condensation reaction is conducted on the second surface, and a third surface is obtained; an organic solution remaining on the third surface is removed, and the copper substrate super-hydrophobic surface is obtained. According to the manufacturing method, the micron-grade coarse structure is built on the surface of the copper substrate, the microstructure of the copper substrate surface is changed, hydroxylation treatment is conducted on the first surface, the condensation reaction is conducted on the second surface, and the free energy of the surface of the copper substrate is lowered, so that the copper substrate has the super-hydrophobic surface and has excellent performance such as antifouling self-cleaning, watertightness, damp resistance, fluid drag reduction and surface protection, and the requirements of materials used in the fields of building materials, biological medicine, fluid transportation and transportation are met.

Description

technical field [0001] The invention relates to the technical field of material surface processing, in particular to a method for preparing a superhydrophobic surface of a copper substrate. Background technique [0002] Superhydrophobic surface refers to a solid surface with a contact angle of water droplets greater than 150 degrees on a solid surface. It has many excellent properties such as anti-fouling self-cleaning, waterproof and moisture-proof, fluid drag reduction, surface protection, etc., and can be widely used in construction materials, biomedicine, etc. , fluid transportation, transportation and many other fields. Among them, whether the solid surface has superhydrophobicity is determined by the surface free energy and surface microscopic morphology of the solid material. By changing the microstructure and surface free energy of the solid surface, the surface of the solid material can be made superhydrophobic. [0003] Metals are widely used in daily life. Howeve...
