Transparent super-hydrophobic film and preparation method and application thereof

Abstract

The invention relates to a transparent super-hydrophobic film and a preparation method and application thereof. The transparent super-hydrophobic film comprises a zinc oxide film and a cetyl trimethoxysilane film loaded on the surface of the zinc oxide film, wherein the transparent super-hydrophobic film is 500 nm to 1000 nm thick, the visible light transmittance is 50% to 90%, the contact angle with water is 165 degrees or above, and the rolling angle with water is 2 degree or blow. The preparation method comprises the following steps: 1, preparing a zinc film by using the RF magnetron sputtering system, and then annealing the zinc film to obtain the zinc oxide film; and 2, modifying the zinc oxide film obtained in the step 1 to obtain the transparent super-hydrophobic film. The transparent super-hydrophobic film is used in building facades, window glass, optoelectronic devices or optical elements. The surface of the transparent super-hydrophobic film is of a nano-rod structure, and the film has excellent super-hydrophobic property, light transmission property, self-cleaning property and anti-fogging property, and can improve light transmittance of glass surface on rainy, snowy and foggy days and reduce glass surface stains.

Description

technical field [0001] The invention relates to the technical field of making a transparent super-hydrophobic film, in particular to a transparent super-hydrophobic film, a method for preparing a transparent super-hydrophobic film based on magnetron sputtering technology, and an application of the transparent super-hydrophobic film. Background technique [0002] The superhydrophobic surface has self-cleaning properties because of its excellent hydrophobic properties, and water droplets can easily roll off and carry away dust. Due to its high transparency, the transparent superhydrophobic surface is expected to be applied on glass exterior walls, automotive glass, and photovoltaic module surfaces. Using its excellent hydrophobic properties, the above-mentioned surfaces have self-cleaning properties, which can improve the protection of automobiles during driving. The visibility of the windshield is clear, the cleaning workload of the glass exterior wall is reduced, and the cle...

AI Technical Summary

Problems solved by technology

The preparation process of sol-gel method and deposition method is complex, and the microscopic convex structure is often uncontrollable, and the film-base binding force is poor

The template method requires a preset template, which is difficult to apply in a large area

The existing methods for preparing super-hydrophobic surfaces have the following problems: 1. The preparation process is complicated, the process control is harsh, and the consistency of the film is poor; 2. The film-base binding force is not strong, so it is difficult to apply to outdoor substrates such as building exterior walls and automotive glass surfaces superior
