Embodiment 1

[0068] Preparation of microstructured glass by hot pressing method: place the shaped prefabricated glass sheet (thickness 170 μm) on the microstructure mold for hot pressing precision molding, such as Figure 4 shown. Place the prefabricated glass sheet on the mold and heat the temperature to 300°C; nitrogen gas is introduced to prevent the mold from being oxidized at high temperature. Through external pressurization and compression molding under 0.5MPa pressure, the microstructure of the mold surface is imprinted onto the surface of the prefabricated glass substrate. Finally, the pressure is released, and the molded prefabricated sheet is cooled to room temperature and released from the mold to obtain a surface with a microstructure. A glass plate with an inverted pyramid microstructure prepared by hot pressing, wherein the angle between the side wall and the bottom surface of the inverted pyramid is 45°, the side length of the bottom surface is 40 μm, and the distance betwe...

Abstract

The disclosure provides a wear-resistant super-amphiphobic self-cleaning film. The wear-resistant super-amphiphobic self-cleaning film has at least a body layer, and the upper surface of the body layer has a plurality of microstructures arranged in an array. The shape of the microstructures is along the A microcavity whose cross-sectional area gradually decreases from the surface of the film to the bottom surface, and the microcavity is filled with superhydrophobic nanomaterials. The disclosure also provides a preparation method of the wear-resistant super amphiphobic self-cleaning film. The wear-resistant super-amphiphobic self-cleaning film of the present disclosure has high universality and versatility. The super-amphiphobic layer of the film is formed by combining the microstructure and super-amphiphobic nanomaterials, which greatly improves the performance of the super-amphiphobic self-cleaning surface. Mechanical stability, which effectively solves the problem that the super-amphiphobic performance, high light transmittance and mechanical stability of the film surface cannot be combined.

Description

technical field [0001] The invention belongs to the field of high-performance materials, and in particular relates to a wear-resistant super-amphiphobic self-cleaning film and a preparation method thereof. Background technique [0002] Inspired by the superhydrophobic material on the surface of the lotus leaf, due to its unique solid-liquid interface properties, it exhibits multiple properties including self-cleaning, low solid-liquid adhesion, and staying dry. It has shown great application prospects in many engineering and technical fields such as surface dust prevention, biological antifouling, fluid drag reduction, enhanced heat and mass transfer, waterproof, anti-icing, and anti-corrosion, and has attracted extensive attention from researchers. However, in practical application scenarios, the surface of objects often faces complex and changeable liquid environments, such as sewage, oil-water mixtures, high-temperature liquids, etc. These liquids have lower surface energ...
