石墨烯作为一种新型二维碳材料,因其独特的结构和优异性质受到广泛关注,在众多领域具有广阔的应用空间。然而由于石墨烯片层间存在较强的相互作用,在实际应用过程中极易发生团聚,从而造成片层利用率低以及性能的急剧降低。因此,利用石墨烯的二维基元结构特点,通过组装实现石墨烯片层的有序性搭接以提高其片层的利用率,对石墨烯材料的实际应用具有重要意义。本文归纳了近年来不断出现的石墨烯基材料的组装体及组装方法,重点介绍了不同形态石墨烯组装体的结构特点及其在电化学储能器件中的潜在应用。
As a new type of two-dimensional carbon material, graphene has attracted a great deal of attention due to its unique structure and excellent properties. It has a wide range of applications in many fields. However, due to the strong interaction between the graphene sheets, agglomeration easily occurs in the actual application process, resulting in low utilization of the sheets and drastic reduction of the performance. Therefore, it is of great significance for the practical application of graphene to utilize the structural features of two-dimensional elements of graphene to achieve the ordered lapping of graphene sheets by assembly to improve the utilization of the sheets. This paper summarizes the assembly and assembly methods of graphene-based materials, which are emerging in recent years. The structural features of different graphene assemblies and their potential applications in electrochemical energy storage devices are emphatically introduced.
