Abstract

The present invention discloses a transparent coating material with a repairable super hydrophobic property. The material is formed by a three-dimensional hollow net-shaped coating combined on a substrate and low surface energy materials filled in gaps, wherein the three-dimensional hollow net-shaped coating is formed by hollow nano tubes of which tube walls have holes and have the thickness of 10-100 nm. The present invention further discloses a preparation method for the coating material. According to the transparent coating material with the repairable super hydrophobic property and the preparation method therefor provided by the present invention, a network of the nano tubes of which the tube walls have the holes is adopted to prepare a transparent silicon dioxide coating, and after the surfaces of the nano tubes are modified by the low surface energy materials and the hole gaps of the nano tubes are filled with the low surface energy material, the coating has a super hydrophobic property and a super hydrophobic self-repairing property; and the thickness of the tube walls of the nano tubes is 10-100 nm, and is less than the wavelength size of visible lights, so that the coating material has relatively high transparency.

Description

technical field [0001] The invention relates to a repairable coating material with both transparency and superhydrophobic performance, and also relates to a preparation method of the coating material, which belongs to the technical field of functional materials. Background technique [0002] Transparent self-cleaning coatings are widely used in the surface protection of transparent materials, and can be used for optical windows of glasses, electronic equipment, and windows of buildings or cars. effect to achieve. The size of the micron structure in the coating is larger than the wavelength of visible light (about 380~760nm), which can cause scattering and reduce the visible light transmittance of the coating; on the other hand, the low surface energy substances on the surface of the coating during use Loss, reducing its superhydrophobic effect, causing the material to lose its self-cleaning performance. In the prior art, the scattering of visible light is reduced and the t...
