Graphene, the strongest, stiffest, and most conductive material known to date, would enable very strong, stiff, and highly conductive materials that would be better than what is available currently. These would be useful in a variety of fields, particularly flexible electronics and aerospace. Thus, to realize this potential, it is necessary to transfer these remarkable properties from graphene nanosheets into macroscopic graphene films. Nacre provides an inspiration for assembling graphene nanosheets into high-performance graphene films by constructing abundant interfacial interactions and a highly aligned structure. However, several issues in the assembly process, including intersheet bonding, dewrinkling, and alignment of graphene nanosheets, have been ignored in descriptions of previously reported macroscopic graphene films. This Review clarifies and compares the interface architecture of macroscopic graphene films described in previous reports. The representative orientation strategies are then summarized and the relationship between alignment and properties is discussed. Finally, perspectives and challenges are proposed to highlight the guidelines on how to construct high-performance graphene films in the future.

高性能石墨烯薄膜的设计原理:界面和排列

石墨烯是迄今为止已知的最坚固,最坚硬和最导电的材料,它将使非常坚固,坚硬和高度导电的材料比目前的材料更好。这些将在各种领域中有用,特别是在柔性电子和航空航天领域。因此,为了实现这一潜力,有必要将这些显着的性能从石墨烯纳米片转移到宏观石墨烯薄膜中。Nacre通过构建丰富的界面相互作用和高度对齐的结构,为将石墨烯纳米片组装成高性能石墨烯薄膜提供了灵感。然而,在组装过程中的几个问题,包括片间粘合,去皱和石墨烯纳米片的排列,在先前报道的宏观石墨烯薄膜的描述中已被忽略。该评论阐明并比较了先前报告中描述的宏观石墨烯薄膜的界面结构。然后总结了代表性的取向策略,并讨论了排列和性质之间的关系。最后,提出了观点和挑战,以突出未来如何构建高性能石墨烯薄膜的指导方针。
