Recent advances on graphene microstructure engineering for propellant-related applications

Abstract

As a special polymeric composite and military-strategic material, composite solid propellant has attracted extensive attention and efforts to improve its performances. Graphene been regarded as an ideal material to enhance the performances of propellants, because of its excellent physical and chemical properties, such as ultra-strong strength, large specific surface area, remarkable thermal conductivity, and phenomenal electrical performance. Moreover, the microstructure engineering based on graphene has been demonstrated to reveal effective influences on the composites. Recently, many new advances have been developed in microstructure engineering of graphene for propellant-related applications. In this article, we first present an overview of the main synthesis methods of graphene. Subsequently, these new advances are reviewed, discussed, and summarized carefully. Finally, the application prospects of microstructure engineering of graphene in the propellant field are proposed.
