Problems solved by technology

[0008] Glass substrate is a material that is widely used at present, such as the display screens of various electronic devices such as smartphones and tablet computers. In order to improve the performance of the glass itself, it is usually necessary to form a coating on the surface during processing, but at present Among the coating materials, most of the coating materials are materials that can be applied to a variety of substrates, and less for special substrates, such as coatings on glass substrates, so that the performance of the coating material itself has certain limitations. limitations, and the optimization of the performance of the glass substrate is also limited

Abstract

The invention provides a hydrophobic surface coating and a preparation method thereof. The hydrophobic surface coating is formed by taking one or more fluorinated alcohol compounds as reaction gas rawmaterials on the surface of a base body through a plasma enhanced chemical vapor deposition method, the fluorinated alcohol compounds have the structural formula of OH-C<n>H<m>F<2n + 1-m>, wherein n>m+1, so that the hydrophobic performance of the surface of the base body is improved, and the hydrophobic surface coating is more suitable for a glass substrate.

Description

technical field [0001] The invention relates to the field of surface coating, and further relates to a hydrophobic surface coating formed by a plasma enhanced chemical vapor deposition method. Background technique [0002] With the improvement of technology level and the expansion of market size, waterproof treatment can be applied to different surfaces, such as: metal, printed circuit board (PCB board), fabric, electronic devices, etc., to give it performance to prevent the surface from water, liquid , rain and other damage, prolong service life and reduce additional costs. [0003] The monomer material used to achieve this type of waterproof effect is at most fluorocarbon materials. Due to low surface energy, strong covalent bonds, zigzag carbon chain structure and helical conformation, fluorocarbon materials can form a negative charge protection at the interface, and are often used in textiles, military, electronics and other fields. At present, the most widely used flu...
