二维石墨烯具有一系列优异的本征性质，然而其大规模应用目前仍没有实现，主要瓶颈在于如何方便且低成本地获得石墨烯宏观体相材料又同时维持单片石墨烯的本征性质，从而在宏观尺度上获得石墨烯的本征性能。针对这一问题，本课题拟研究发展以相互独立的单层石墨烯作为结构（聚合）单元通过边缘自交联的方式，便利、低成本和可控地制备类高分子三维交联石墨烯宏观体相材料的原理、方法和工艺；理解和掌握多种石墨烯（单元的）结构和工艺条件对材料制备的影响机制；实现对石墨烯宏观体相材料的宏观/微观结构及形貌的调控，从而达到优化和调控其性能的目的。在此材料基础上系统研究石墨烯宏观体的性能和本征石墨烯性质之间的相互关系，进一步开展这种材料的应用研究，特别是重点开展基于其特别的光电性能和机械性能等在非常规催化、光电、储能等方面的应用研究。

Though two dimensional graphene has a series of excellent intrinsic properties, its large-scale applications haven’t been realized. The main bottleneck is how to conveniently and low-costly prepare the macroscopic graphene bulk material retaining the intrinsic properties of the individual graphene sheets. And numerous superior intrinsic properties of graphene will be manifested on a macroscopic scale. To this end, this proposal will study and develop the principle, method and technique for the convenient, low-cost and controllable preparation of polymer-like three-dimensional cross-linked graphene bulk material, in which the building units are independent and individual single-layer graphene sheets covalently self-cross-linked together through the chemical bonds located mostly on the graphene sheets edges. Then we will study to understand the influencing mechanism for material preparation of different graphene sheets under different technique conditions. Furtherly, the optimization and control of the macroscopic graphene bulk material’s performance will be achieved through the adjustment and control of macro/micro-structure and morphology of the material. Based on the above graphene bulk material, we will comprehensively study the relationship between the intrinsic properties of individual graphene sheets and the performance of the macroscopic graphene bulk material. Many application researches, especially unconventional catalysis, optoelectronic application and energy storage, will furtherly be carried out based on the material’s special optoelectronic properties, mechanical properties, etc.
