Embodiment 1

[0034] The preparation of embodiment 1 transparent super-amphiphobic coating

[0035] (1) Using water as a solvent, a 50nm monodispersed polystyrene microsphere emulsion is prepared into a liquid A with a mass concentration of 5%;

[0036] (2) Mix 0.2g of ethyl orthosilicate, 0.2g of 0.1mol / L hydrochloric acid, and 0.3g of absolute ethanol in the sample bottle to prepare liquid B;

[0037] (3) 5g of deionized water and 0.2g of B solution were added to 1g of solution A, followed by continuous stirring for 45min in a magnetic stirrer, and a partially hydrolyzed and cross-linked polystyrene sol-gel prepolymer solution was obtained after stirring. The bulk solution was ultrasonically dispersed (100W) for 15 minutes to prepare a transparent super-amphiphobic coating;

[0038](4) Spray the obtained transparent super-amphiphobic coating on the surface of the glass substrate: place the super-amphiphobic coating (ie, the prepolymer solution after ultrasonic dispersion) under a pressur...

Embodiment 2

[0048] The preparation of embodiment 2 transparent super-amphiphobic coating

[0049] The preparation method is the same as that of Example 1, and the difference from Example 1 is that: liquid A is a 50 nm monodispersed polystyrene microsphere solution with a mass concentration of 0.1%.

[0050] The test results of scanning electron microscope, wettability, transmittance, heat resistance test, friction resistance and other test results are consistent with those of Example 1.

Embodiment 3

[0051] The preparation of embodiment 3 transparent super-amphiphobic coating

[0052] The difference from Example 1 is that: Liquid A is a 50 nm monodispersed polystyrene microsphere solution with a mass concentration of 10%.

[0053] The test results of scanning electron microscope, wettability, transmittance, heat resistance test, friction resistance and other test results are consistent with those of Example 1.

Abstract

The invention belongs to the technical field of super-amphiphobic materials, and in particular relates to a method for preparing a transparent super-amphiphobic material. The transparent super-amphiphobic material prepared by the invention includes a transparent super-amphiphobic coating and the transparent super-amphiphobic coating by spraying etc. The transparent super-amphiphobic coating prepared by the method. The material used in the invention is simple, the cost is low, the preparation process is simple, the operability is strong, the preparation method is easy to realize, and the industrialization and large-scale production are easy. The prepared coating has excellent super-hydrophobic and super-oleophobic properties, high transparency, good thermal and mechanical stability, and can be used in automotive windshields, solar panels, mobile phone screens and optical devices. . Moreover, the present invention can prepare the transparent super-amphiphobic coating on a large scale by spraying, and can be applied to any flat and curved surfaces.

Description

technical field [0001] The invention belongs to the technical field of super-amphiphobic materials, and in particular relates to a preparation method of a transparent super-amphiphobic material. Background technique [0002] Many organisms in nature have excellent self-cleaning ability, among which the lotus leaf has become the most famous example with the "self-cleaning" effect of oozing out mud without staining. After research, it is found that the surface of lotus leaf is composed of materials with certain roughness and low surface energy. By imitating this natural surface self-cleaning effect, various applications in anti-fouling, anti-corrosion, anti-icing and other fields have been designed and produced. artificial self-cleaning surfaces. Among them, the most common is superhydrophobic coating. Although superhydrophobic coatings have high contact angles and low rolling angles for water droplets, they are easily wetted by oil or other droplets with low surface tension...
