A laser preparation method of self-cleaning antibacterial glass

Abstract

The invention discloses a laser preparation method of self-cleaning antibacterial glass. First, the prepared chemical solution is washed onto the surface of the metal substrate, and the bottom surface of the glass is covered with the metal substrate; thirdly, the ultrafast laser is used to penetrate the glass to irradiate the metal substrate, the glass at the interface is melted, and the microstructure on the metal is transferred to the glass. At the same time, the nanoparticles in the solution are reduced and adsorbed on the glass microstructure, and then the glass is annealed to form a double-sized micro-nanostructure covering the non-polar nanoparticles on the glass surface. The surface has an excellent self-cleaning super-hydrophobic function. It can remove oil stains on the glass surface with a small amount of water and labor, and there is almost no water stain residue, which reduces the difficulty of cleaning during use. Moreover, the superhydrophobic property can resist bacterial adhesion, and the nanoparticles can kill the adhered bacteria, thus making the glass surface have excellent antibacterial / bactericidal function. The preparation method of the invention is simple, has universal applicability, and is applicable to glasses of various materials. Moreover, the mechanical properties of the prepared glass are unchanged, the light transmittance is good, and the glass 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...

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
