摘　　要：玻璃是一种历史悠久、用途广泛的无定形硅酸盐材料,而石墨烯则是近年来发现的仅由碳原子组成的二维层状材料。石墨烯具有超高的机械强度、导电性、导热性和透明性,恰好与传统的玻璃形成互补。将石墨烯与玻璃结合在一起,在保持透明性的基础上,同时赋予普通玻璃导电性、导热性和表面疏水性,具有非常重要的实际意义和理论价值。相比于液相涂膜或者转移的方法,直接在玻璃表面生长石墨烯能够从根本上避免由于污染和破损引起的石墨烯性能的下降,从而发展出一种新型材料——石墨烯玻璃。本文介绍了我们研究组在各种玻璃表面直接生长石墨烯的研究进展,其中包括石墨烯在固态耐高温玻璃和熔融态玻璃表面的高温生长,以及利用等离子体辅助手段实现石墨烯在普通玻璃表面的低温生长,并以此为基础发展出多种基于石墨烯玻璃的应用实例。总结展望了石墨烯玻璃的制备和应用的未来挑战与发展方向。Glass, an amorphous oxide material with a long history, is widely used in our daily life. Graphene is a novel two-dimensional material formed by carbon atoms. The unique properties of graphene, such as excellent mechanical strength, high electrical and thermal conductivity and optical transparency, serve as complementary components to those of glass. Therefore, the combination of graphene and glass would endow noticeable electrical/thermal conductivity and surface hydrophobicity without sacrificing the transparency of conventional glass. Previously reported routes for integrating graphene with glass mainly used solution-casting of liquid-exfoliated graphene nanoplatelets and transfer-coating of graphene films grown on metals. Compared with the existing methods, the direct growth of graphene on glass could avoid contamination and damage during the integration process, thereby resulting in good graphene quality and scalability, high thickness/ coverage uniformity, much reduced breakage density, and a tight and clean interface with the underlying glass. In this article, we review our recent progress on the direct growth of graphene on various glass by chemical vapor deposition （CVD）. With the consideration of the thermo-stabilities of glass and application requirements, three different CVD routes are developed, i.e., high-temperature, atmospheric pressure CVD on solid-state thermostable glass and molten-state glass, as well as low-temperature plasma enhanced CVD on solid-state soda-lime floating glass. We also explore the practical applications of the as-grown graphene glass where electrochromic windows, defoggers, cell proliferation, and photocatalytic plates were fabricated based on our CVD-grown graphene glass. The high performance of these devices promises practical usage of graphene glass in daily-life applications.
