摘要: 氢能是改善国内能源结构、实现碳达峰和碳中和目标的重要举措。储氢瓶是氢能发展的关键技术之一。为了提高储氢瓶的质量储氢密度,采用聚合物内衬的轻量化Ⅳ型瓶成为重点发展方向。然而,聚合物内衬的气体阻隔性能成为了限制储氢瓶发展的核心指标。本文阐述了石墨烯提高聚合物气体阻隔性能的机理,归纳了二相和三相气体渗透理论模型,基于石墨烯的化学结构、改性分散、诱导聚合物结晶、取向四个方面总结了石墨烯/聚合物复合材料的气体阻隔性能,在此基础上展望了未来的研究方向。

Abstract: Hydrogen energy is an important measure to improve the domestic energy structure and achieve the goals of carbon emission peak and carbon neutrality. Hydrogen storage tanks are one of the key technologies for the development of hydrogen energy. To improve the gravimetric hydrogen densities of hydrogen storage tanks, lightweight type IV tanks with polymer liners have become the key development direction. However, the gas barrier performance of polymer liners has become the core index limiting the development of hydrogen storage tanks. In this paper, the mechanism of graphene improving the gas barrier performance of polymers is expounded, and the theoretical permeation models for two-phase and three-phase composites are summarized. The gas barrier properties of graphene-reinforced polymer matrix composites are outlined based on the chemical structures, modified dispersion, induced polymer crystallization and orientation of graphene. On this basis, future research directions have been prospected.
