Good thermal conductivity of graphene. Recently, a group of Peking University using chemical vapor deposition method, by optimizing the growth conditions, the successful implementation of graphene in the glass surface of the direct growth is expected to speed up the integration of graphene materials and glass industry to promote the large-scale application of graphene glass. The material can also be applied to the thermal components of LED luminaires, including lampholders, cooling lamp cups and lamp housings. Recently, the well-known academic journal "natural materials" on the latest research was reported. Glass is one of the traditional building materials with low cost and good light transmission. Graphene is a carbon material with a single-layer sheet structure composed of carbon atoms, and is the thinnest and hardest conductive material currently known at room temperature The best and most flexible nanomaterials. The new composite graphene glass produced by combining graphene and glass will greatly expand the application space of glass and lead to the revolutionary transformation of the glass industry from large quantities of low added value applications to economical and high added value applications. Graphene glass is commonly used as a liquid coating or transfer method. The graphene film obtained in this way inevitably has the problem of surface interface contamination, which seriously affects the performance of the graphene glass. At the same time, the traditional preparation methods are complicated to operate, high in cost and low in yield, which is also difficult to meet the needs of large-scale applications. Therefore, the development of a new method for the direct growth of graphene on glass substrates is an important issue in the current related research. Therefore, a long-term research team led by Academician Liu Zhongfan of Peking University's School of Chemistry and Molecular Engineering has successfully overcome the problems of low catalytic activity of precursor on glass surface through precise control of reaction gas concentration, growth temperature and growth time. Migration ability is weak and other difficult problems, high-quality graphene film controlled growth in high temperature glass and ordinary glass successfully achieved. The experiment proves that, under the condition of graphene growth, common glass exists in a molten state, the surface height is uniform and isotropic. The group used these properties of molten glass to achieve the growth of graphene wafers of uniform size and distribution. The graphene glass obtained by the direct growth method has excellent properties such as good interface between the glass and the graphene and no pollution at the interface. It is understood that the graphene glass has the advantages of both glass transparency, graphene's electrical conductivity, thermal conductivity and surface hydrophobicity, and can be applied to thermochromic windows, anti-fog windows and photocatalysis in the future. Academician Liu Zhongfan said that it is believed that graphene glass will have a very broad application prospect in the future and is very important for the glass industry and graphene materials. As a unique and advanced carbon material, graphene is setting off a disruptive industrial revolution sweeping the globe with promising future market.
