Abstract Synthesis of graphene at high temperature offers an alternative route for large-scale production on a short time scale. Through the solid-state exothermic reaction of the polytetrafluoroethylene (PTFE)-Al energetic material, single and few-layer graphene having a lateral size in tens of nanometers are produced with an ultralow power consumption due to the self-sustained characteristics of the reaction. The graphene can directly disperse in ethanol to form stable dispersion and by evaluating in half-cell configuration, the graphene exhibits a stable cycling performance over 1000 cycles. The positive correlation between the dimension of the PTFE precursor and graphene demonstrates the feasibility of synthesizing powdered graphene in a controllable manner.

用于可扩展石墨烯生产的自持固态放热反应

摘要 高温合成石墨烯为短时间大规模生产提供了一条替代途径。通过聚四氟乙烯（PTFE）-Al含能材料的固态放热反应，由于反应的自持特性，可以以超低功耗生产单层和少层的横向尺寸为数十纳米的石墨烯。石墨烯可以直接分散在乙醇中形成稳定的分散体，通过半电池配置评估，石墨烯表现出超过 1000 次循环的稳定循环性能。PTFE 前驱体与石墨烯的尺寸之间的正相关证明了以可控方式合成粉状石墨烯的可行性。
