能源危机和环境污染导致了世界范围内对储能新材料的开发和环境保护的双重压力。石墨烯具有优异的力学性能和电化学性能，被认为是解决这些问题的一种很有前途的材料，可应用于能量储存和转换、海水淡化等领域，特别是近年来随着人们对柔性、便携式器件的需求，开发柔性、自支撑的材料成为研究的热点和难点。因此，近年来国内外对石墨烯基自支撑可弯曲薄膜的研究很多，本文综述了石墨烯基自支撑可弯曲薄膜的研究进展，包括制备技术和应用。介绍了真空过滤法、层层自组装法、真空辅助自组装法、机械压缩法和溶剂挥发法等五种制备方法。在应用部分，讨论了石墨烯基自支撑可弯曲薄膜在储能和环保方面的应用现状和面临的挑战。
Energy crisis and environmental pollution lead to the dual pressures of worldwide exploration for new materials applied in energy storage and environmental protection. Graphene with excellent mechanical and electrochemical properties is considered a promising material to solve these problems by applying in energy storage and conversion, desalination and so on. Particularly, with the demand for flexible, portable devices in recent years, developing flexible, self-supporting materials is a hot but difficult spot. Therefore, there are a lot of researches on developing the graphene-based free-standing bendable film in recent years and its advance is reviewed in this paper, which includes fabricating techniques and applications. The preparation methods are categorized into five types to introduce, including vacuum filtration, layer-by-layer self-assembly, vacuum-assisted self-assembly, mechanical compression, and solvent evaporation. In the part of applications, the current applications and challenges of graphene-based free-standing bendable films in energy storage and environmental protection are discussed.
