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.

能源危机和环境污染导致世界范围内探索用于储能和环境保护的新材料的双重压力。具有优异的机械和电化学性能的石墨烯被认为是通过在能量存储和转化，脱盐等方面的应用来解决这些问题的有前途的材料。特别地，随着近年来对柔性便携式设备的需求，开发柔性，自支撑材料是热门但困难的领域。因此，近年来对开发石墨烯基自支撑可弯曲薄膜的研究很多，本文对它的研究进展进行了综述，包括制备技术和应用。制备方法分为五种，包括真空过滤，逐层自组装，真空辅助自组装，机械压缩和溶剂蒸发。在应用部分中，讨论了石墨烯基独立式可弯曲薄膜在储能和环境保护方面的当前应用和面临的挑战。
