Laser preparation method of self-cleaning antibacterial glass

Abstract

The invention discloses a laser preparation method of self-cleaning antibacterial glass. Firstly, a prepared chemical solution is scoured to the surface of a metal substrate, and meanwhile, the bottomsurface of glass covers the metal substrate; thirdly, ultrafast laser penetrates through the glass to irradiate the metal substrate, the glass at the interface is molten, the microstructure on the metal is transferred to the glass, meanwhile, the nanoparticles in the solution are reduced and adsorbed to the glass microstructure, and then the glass is subjected to annealing treatment, so that a dual-size micro-nano structure covering the non-polar nanoparticles is generated on the surface of the glass. The surface has an excellent self-cleaning super-hydrophobic function, greasy dirt and the like on the surface of the glass can be removed by using a small amount of water and labor, almost no water stain is left, and the cleaning difficulty in the using process is reduced. Moreover, the super-hydrophobic property can resist bacterial adhesion, and the nanoparticles can kill the adhered bacteria, so that the surface of the glass has excellent antibacterial/bactericidal functions. The preparation method is simple, has universality and is suitable for glass made of various materials. The prepared glass has the advantages of unchanged mechanical properties and favorable light permeability, and is suitable for large-scale commercial production.

Description

technical field [0001] The invention relates to a laser preparation method of self-cleaning antibacterial glass, which belongs to the technical field of glass manufacturing. Background technique [0002] With the gradual improvement of people's material and cultural life, people pay more and more attention to environmental sanitation and the cleanliness of human body contact surfaces. In the field of using glass as a countertop, such as coffee table worktops, dining table worktops, kitchen worktops and electronic scale covers installed on electronic scales, glass tables are easy to contact with various oils and other liquids. Wipe to clean, the user's work intensity is high, and the cleaning is not thorough. Most of the existing self-cleaning glass surfaces are super-hydrophilic coated glass, which requires a large impulse water flow to achieve a good cleaning effect. [0003] In addition, the glass platforms in these home areas are often in a humid environment and are oft...

AI Technical Summary

Problems solved by technology

Although it has been reported that ultrafast lasers can be used to fabricate microstructures on glass surfaces, due to the light transparency of glass, the types of microstructures processed are limited, and after the laser reaches the glass surface for material removal and structure induction, the remaining laser energy It will pass through the glass to generate heat on the processing platform, which is easy to cause thermal damage to the glass surface

In addition, in order to obtain the antibacterial function of the glass, it is necessary to add processes such as coating, which increases the difficulty of processing
