摘　　要：氟化石墨烯(FG)作为一种重要的石墨烯衍生物材料已在介电材料、超润滑、生物材料、电子器件领域展现出良好的应用前景。因其C—F键的高键能、高官能化密度、高温裂解可产生高活性含氟自由基以及二维片层结构等特点,FG有望作为高性能的包覆剂/氧化剂等应用于含能材料、固体推进剂等领域。近10年以来,基于直接氟化技术制备FG方面已报道了一系列研究工作,但在含能材料、固体推进剂领域实质性研究明显不足。文章主要综述了有关FG的宏量制备、FG直接氟化反应历程、FG的应用拓展等方面的研究成果,并对FG的未来发展方向以及在含能材料、固体推进剂领域的潜在应用提出了展望和建议。相关研究成果可为FG在固体推进剂领域的应用提供新材料设计与研究基础,并可为探究FG改进固体推进剂的原理以及性能优化提供新材料及其制备新途径。As an important graphene derivative,fluorinated graphene(FG)shows a good application prospect in the fields of dielectric materials,superlubricity,biomaterials and electronic devices.Due to the high C—F bonding energy,high functionaliza⁃tion density and high activity of fluorine⁃containing free radicals produced by pyrolysis and two⁃dimensional lamellar structure,FG is hopeful to be applied in energetic materials and solid propellants as a high⁃performance coating agent/oxidant.In the latest 10 years,a series of work on the preparation of FG based on the direct fluorination technology have been reported,but substantial re⁃search in the field of energetic materials and solid propellant is obviously insufficient.Research progress on the mass production,the direct gas fluorination process and the application expansion of FG was briefly reviewed.Prospects and suggestions for the future de⁃velopment of FG and its potential applications in the fields of energetic materials and solid propellants were put forwarded.The rele⁃vant results may provide material design and research foundations for the application of FG in the field of solid propellant,and pro⁃vide a new material foundation together with its preparation methods for the principle and performance optimization of the FG modi⁃fied solid propellant.
