Abstract

The invention belongs to the field of preparation of micro or / and nano-structures on surfaces of solids and specifically relates to a copper-based super-hydrophobic composite film with a low friction coefficient and a preparation method thereof. The copper-based super-hydrophobic composite film with the low friction coefficient is characterized in that a composite structure with a micro-scale cuprous oxide crystal structure and submicro-scale metal silver particles is firstly formed on the surface of a copper-based material, and then surface chemical modification is performed to obtain a product. Each contact angle between the copper-based super-hydrophobic composite film with the low friction coefficient and water exceeds 150 degrees, the friction coefficient is low (can be as low as about 0.1) and can be stably kept, and the copper-based super-hydrophobic composite film has good super-hydrophobic performance and relatively low friction coefficient.

Description

technical field

[0001] The invention belongs to the field of preparing micron or / and nanostructures on solid surfaces, and in particular relates to a copper-based super-hydrophobic composite film with a low coefficient of friction and a preparation method thereof. Background technique

[0002] In recent years, superhydrophobic surfaces have attracted widespread attention because of their unique properties and promising prospects in basic research and industrial applications. During the use of metal, it consumes a lot due to corrosion, friction and wear. Since the superhydrophobic surface can provide useful ideas for metal anti-corrosion and metal wear reduction and anti-wear, it is particularly important to research and develop a metal-based superhydrophobic surface with good tribological properties and its preparation method.

[0003] As an important engineering material, metallic copper plays an important role in people's daily life and industrial production. Constructin...
