Problems solved by technology

This method is similar to the metal-catalyzed epitaxial growth method, and its advantage is that it can be carried out at a lower temperature, thereby reducing the energy consumption in the preparation process, but it needs to separate the graphene from the substrate, such as graphene and the substrate through chemical The method of corroding metal is easy to separate, and the graphene needs to be processed later before it can be applied. The transfer process of graphene is complicated
[0004] The snow and fog removal of architectural glass is generally manual, which is time-consuming and labor-intensive, especially the cleaning of high-rise buildings has potential safety hazards
Due to its particularity, the front windshield of a car needs to increase its mechanical strength, especially when it breaks during high-speed movement, the splashed glass will pose a serious threat to the lives of members of the car and pedestrians

Abstract

Provided are preparation and application of CVD graphene composite glass. The preparation of the CVD graphene composite glass comprises the steps of: depositing a graphene CVD film on a surface of glass, covering the side, where the graphene CVD film is arranged, of the glass with another piece of glass, and folding the two pieces of glass together for fixation so as to form a glass-graphene-glasswhole body; and adding electrodes to the graphene CVD film between the two layers of glass and applying a voltage , so as to generate heat and reach a temperature of 50-75 DEG C within 1-3 seconds. According to the preparation and application of the CVD graphene composite glass, a uniform electric conduction and thermal conduction path is formed in the graphene CVD film by utilizing the characteristics of a high specific surface area and a two-dimensional nano structure of graphene, and the temperature can be increased rapidly after the voltage is applied; due to the characteristic of single-layer graphene transparency of the graphene CVD film, the prepared heat-generating glass has great application to snow and frost removal of a car front windshield in winter and fields of removal of snow and frost for houses; and due to the single-layer graphene effect of the graphene CVD film, real-time three-dimensional information can be generated by using a computer, and thus the graphene CVD film can be applied to a glass augmented reality technology.
