Abstract

The invention discloses a preparation method of super-hydrophobic self-cleaning glass based on a ZnO nano array coating. The preparation method comprises the following steps: preparing ZnO seed layer sol by a sol-gel method; plating ITO glass with a ZnO seed layer by a dipping-pulling method; performing heat treatment and paving a layer of polystyrene spheres; performing hydrothermal treatment on the prepared ZnO seed layer/PS material in a ZnO growth solution to obtain a ZnO/PS nano rod array; and treating the ZnO/PS nano rod array with toluene for a period of time to obtain the super-hydrophobic self-cleaning glass. According to the super-hydrophobic self-cleaning glass based on a ZnO nano array coating prepared by the method disclosed by the invention, the transmittance of visible light can reach 96.3%, and both of the ultraviolet absorption efficiency and shielding efficiency can reach 90%; and according to the test by a contact angle meter (DSA series), the contact angle to water exceeds 152 degrees. The preparation method disclosed by the invention has the advantages of no secondary harm, low cost, easiness in implementation and convenience in control.

Description

technical field [0001] The invention belongs to the field of preparation of self-cleaning functional coating materials, in particular to a preparation method of superhydrophobic self-cleaning glass based on ZnO nano-array coating. Background technique [0002] Self-cleaning functional glass means that ordinary glass has unique physical properties on its surface after being treated by special physical or chemical methods. It no longer needs to be cleaned by traditional manual scrubbing but can be cleaned under the action of natural rainwater. coated glass. With the development of modern cities, glass curtain wall, as a beautiful and novel way of building wall decoration, has become a prominent feature of the era of modern high-rise and super high-rise buildings. However, although ordinary glass is naturally beautiful, it is not resistant to pollution. Especially with the increasing environmental pollution, there is a lot of dust in the atmosphere, and the glass curtain wall ...
