Although many great potential applications are proposed for graphene, till now none are yet realized as a stellar application. The most challenging issue for such practical applications is to figure out how to prepare graphene bulk materials while maintaining the unique two-dimensional (2D) structure and the many excellent properties of graphene sheets. Herein, such polymeric graphene bulk materials containing three-dimensional (3D) cross-linked networks with graphene sheets as the building unit are reviewed. The theoretical research on various proposed structures of graphene bulk materials is summarized first. Then, the synthesis or fabrication of these graphene materials is described, which comprises mainly two approaches: chemical vapor deposition and cross-linking using graphene oxide directly. Finally, some exotic and exciting potential applications of these graphene bulk materials are presented.
尽管人们提出了许多关于石墨烯的潜在应用，但到目前为止，还没有一种应用能够真正实现。对于这类实际应用来说，最具挑战性的问题是如何在保持石墨烯片独特的二维（2D）结构和众多优异性能的同时，制备出大块的石墨烯材料。本文综述了含有三维（3D）交联网络的聚合物石墨烯块状材料，其中石墨烯片作为构建单元。首先总结了各种提出的石墨烯块状材料结构的理论研究。然后，描述了这些石墨烯材料的合成或制备，主要包括两种方法：化学气相沉积和直接使用氧化石墨烯交联。最后介绍了这些石墨烯块状材料的一些奇特而令人兴奋的潜在应用。
