石墨烯及其衍生物（G）是有前景的纳米填料，尽管添加量较低，但由于其综合优异的性能，能够提高复合材料的多功能性能。此外，与随机分布G的复合材料相比，将G排列到各种基体中可以实现更强的性能改善。排列G是充分利用其性能的有效策略。在目前的工作中，全面回顾了定向石墨烯（和定向石墨烯衍生物）复合材料（AGC）的制备和所得性能的最新进展。介绍了聚合物基和金属基 AGC 的各种制备方法的机理，例如液晶法、真空过滤法以及真空过滤和放电等离子体烧结法的组合。进一步分析了程序中的相关影响因素。此外，还讨论了定向石墨烯（和定向石墨烯衍生物）对电性能、热性能和机械性能的影响，并总结了AGC具有更好性能的原因。讨论了当前与 AGC 相关的挑战以及 AGC 未来进展的途径。
Graphene and its derivatives (G) are promising nanofillers with the ability to boost versatile properties of composites despite the low addition due to their combined excellent performances. Moreover, aligning G into various matrices can achieve stronger improvement in properties compared to composites with randomly distributed G. Aligning G is an effective strategy to take full advantage of its properties. In the present work, the state-of-the-art progress in preparations and resulted properties of aligned-graphene (and aligned-graphene derivatives) composites (AGCs) is comprehensively reviewed. The mechanisms of various preparation methods are presented, such as liquid crystal method, vacuum filtration method, and combinations of vacuum filtration and spark plasma sintering method, for both polymer-based and metal-based AGCs. Furthermore, the relevant influencing factors in procedures are analyzed. In addition, influences of aligned-graphene (and aligned-graphene derivatives) on the resulting electric, thermal, and mechanical properties have been discussed and the reasons why AGCs possessed better properties have been summarized. Current challenges associated with AGCs and the pathways toward future progress in AGCs are discussed.
