Title:
SUPER-HYDROPHOBIC BIONIC NANO-COATING FOR DISPLAY SUPPORT FRAME AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/236621
Kind Code:
A1
Abstract:
The present invention relates to the technical field of display support frames. Disclosed is a preparation method for a super-hydrophobic bionic nano-coating. The method comprises the following steps: firstly, etching a micro-nano structure on the surface of a hydrophobic substrate by means of an etching process, and then cleaning the etched surface of the hydrophobic substrate; next, coating the surface of the hydrophobic substrate with an adhesive layer; and finally, spraying nano-scale hydrophobic coating particles onto the adhesive layer, and drying same to obtain a super-hydrophobic layer. In the present invention, periodic micron dot matrices are etched on the surface of a hydrophobic substrate by using an etching technique, and in combination with an adhesive and nano-scale hydrophobic coating particles, the surfaces of the dot matrices are covered and wrapped by the sprayed nano-scale hydrophobic coating particles, such that the substrate surface, which has a dot matrix structure, is completely adhered to the nano-scale hydrophobic coating particles; therefore, the dot matrices and a super-hydrophobic layer formed on the surface form a micro-nano composite structure, which enables the surface of the substrate to maintain hydrophobic characteristics for a long time.
