The direct growth of graphene on low‐cost soda‐lime glass has attracted widespread attention for its potential to promote the development of high‐value‐added graphene‐based products. For its most promising application as a transparent electrode, a relatively low sheet resistance is highly desired for the derived graphene glass. However, obtaining this result is still a challenge owing to the low catalytic activity of the glass surface, the small domain size of the resultant graphene, and the limited film continuity. Carbon nanotubes (CNT), which have similar structural and electronic properties to those of graphene, have been proposed to bridge/offset the grain boundaries and defects of graphene to improve electron transfer and reduce the sheet resistance. To achieve this, the one‐batch synthesis of highly conductive graphene and multiwalled CNT (MWCNT) hybrid films on soda‐lime glass using a molten‐bed chemical vapor deposition (CVD) method is designed. The thus‐obtained glass exhibits excellent conductivity, transmittance, and outstanding thermal and chemical stability. This highly conductive hybrid material is then employed as a high‐performance liquid‐crystal‐based switchable window. In short, this work is believed to enhance the versatile applications of highly conductive graphene/MWCNT‐hybrid‐coated glass as well as its mass production, considering its compatibility with current glass production techniques.

在透明导电应用的钠钙玻璃上一步生长石墨烯/碳纳米管杂化膜

低成本钠钙玻璃上石墨烯的直接增长因其促进高附加值石墨烯基产品开发的潜力而受到广泛关注。对于其作为透明电极的最有希望的应用,对于衍生的石墨烯玻璃非常需要较低的薄层电阻。然而,由于玻璃表面的催化活性低,所得石墨烯的畴尺寸小以及膜的连续性有限,因此获得该结果仍然是一个挑战。已经提出具有与石墨烯相似的结构和电子特性的碳纳米管(CNT),以桥接/抵消石墨烯的晶界和缺陷,以改善电子传递并降低薄层电阻。为达到这个,设计了使用熔融床化学气相沉积(CVD)方法在钠钙玻璃上单批合成高导电性石墨烯和多壁CNT(MWCNT)杂化膜的方法。如此获得的玻璃具有出色的电导率,透射率以及出色的热稳定性和化学稳定性。然后,将这种高导电性的混合材料用作高性能基于液晶的可切换窗口。简而言之,考虑到与当前玻璃生产技术的兼容性,这项工作被认为可以增强高导电性石墨烯/ MWCNT混合涂层玻璃的通用性及其大规模生产。以及出色的热和化学稳定性。然后,将这种高导电性的混合材料用作高性能基于液晶的可切换窗口。简而言之,考虑到与当前玻璃生产技术的兼容性,这项工作被认为可以增强高导电性石墨烯/ MWCNT混合涂层玻璃的通用性及其大规模生产。以及出色的热和化学稳定性。然后,将这种高导电性的混合材料用作高性能基于液晶的可切换窗口。简而言之,考虑到与当前玻璃生产技术的兼容性,这项工作被认为可以增强高导电性石墨烯/ MWCNT混合涂层玻璃的通用性及其大规模生产。
