Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "fixed", "integrated", "left", "right" and si...

Abstract

The invention discloses a preparation method for improving metal hydrophobicity based on a vapor deposition method. The method comprises the steps that 1, the surface oxidation control method is utilized for generating an oxidation metal film on the metal surface; and 2, hexamethyldisilane modifies oxidation metal through the vapor deposition method. By using the manufacturing method of super-hydrophobic metal, surface hydrophobicity of the metal is improved correspondingly, the hexamethyldisilane is cheap and low in toxicity compared with chlorine and fluorine containing reagent, and is friendly to environment, thus the metal does not corrode easily in the humid environment, or does not frost or freeze easily at the low temperature, thus heat conduction to the metal is avoided, the influence on electricity conducting performance is avoided, the stability of metal products and devices is improved directly and substantially, and the property of people and social safety are guaranteed.

Description

technical field [0001] The invention relates to a preparation method for improving metal hydrophobicity based on a vapor deposition method. Background technique [0002] Metal copper is often used in industry and daily life. It has good electrical conductivity, thermal conductivity and ductility, and is mainly used in power electronics, transportation construction, aerospace and many other fields. However, copper is prone to corrosion in humid environments, and it is easy to frost and freeze at low temperatures, which will affect its thermal conductivity and electrical conductivity. The emergence of these problems will lead to a decline in the stability of copper products and devices, causing damage to people's property and social security. [0003] In 1952, Ward et al. first recorded the superhydrophobic phenomenon on the surface of lotus leaves. In the 1960s, researchers discovered that the hydrophobic and self-cleaning functions of lotus leaves are due to the microstru...
