Problems solved by technology

However, elastomers have their obvious disadvantages. For example, elastomers are amorphous. Under variable ambient temperatures, the micro-nano structures constructed by elastomers are more likely to collapse and become unstable, thus making the constructed surface lose superhydrophobic properties

Abstract

The invention discloses a transparent antibacterial super-hydrophobic coating and a preparation method thereof. The transparent antibacterial super-hydrophobic coating consists of polystyrene nanospheres and PS-TiO2 structural composite particles, after the polystyrene nanospheres are etched by virtue of concentrated sulfuric acid, the polystyrene nanospheres are hydrolyzed and condensed with nanozinc oxide and tetrabutyl titanate to prepare the PS-TiO2 structural composite particles, and the surface of the PS-TiO2 structural composite particle is hydrophobized by virtue of octyltriethoxysilane, so that a transparent antibacterial super-hydrophobic coating is formed. The coating prepared by the invention is high in strength and high in hydrophobic capability, and the obtained super-hydrophobic surface is bacteria-free and excellent in stability.

Description

technical field [0001] The invention relates to the technical field of hydrophobic coating materials, in particular to a transparent antibacterial superhydrophobic coating and a preparation method thereof. Background technique [0002] Since the discovery of superhydrophobic and self-cleaning properties on the surface of lotus leaves, the research on bionic superhydrophobic surfaces has aroused intense research interest of many researchers. Recent studies have shown that the construction of superhydrophobic surfaces can endow materials with excellent biocompatibility Such as anti-protein adsorption, anti-platelet adhesion, anti-bacterial adhesion, etc. [0003] Ordinary transparent superhydrophobic coatings have good visible light permeability and hydrophobicity, and have been used in various daily necessities, such as windshields of automobiles, airplanes, and spacecraft. When rain falls on the glass, it will It rolls off quickly without sticking to the glass, and at the s...
