Abstract

Graphene oxide (GO) membranes offer high selectivity and energy-efficient gas separation. However, their dense, layered structure and tortuous diffusion paths limit permeability, posing a barrier to industrial use. Here we present a method to enhance selectivity and permeability, maintaining the structural stability of such membranes. With an industrially friendly manufacturing method, we produce crumpled GO membranes with gas diffusion pathways controlled by a multidomain structure. These membranes achieve H₂ permeability of approximately 2.1 × 10⁴ barrer, significantly surpassing the permeability of flat lamellar GO membranes, which is below 100 barrer. Its H₂/CO₂ selectivity of 91 outperforms current membrane technologies. In addition, the crumpled membranes demonstrate stability under harsh conditions (−20 °C, 96% relative humidity), a critical requirement for practical applications. This work addresses the long-standing permeability–selectivity trade-off and establishes a robust, scalable platform for integrating two-dimensional materials into membrane technology for real-world applications.

应变诱导的氧化石墨烯薄片的皱缩，以实现H2和CO2的快速和选择性运输

氧化石墨烯（GO）膜提供高选择性和节能气体分离。然而，它们致密的层状结构和曲折的扩散路径限制了渗透率，对工业应用构成了障碍。在这里，我们提出了一种方法来提高选择性和通透性，保持这种膜的结构稳定性。通过工业友好的制造方法，我们生产出具有多畴结构控制的气体扩散路径的皱褶氧化石墨烯膜。这些膜的H2渗透率约为2.1 × 104巴阻，显著超过了平板层状氧化石墨烯膜的渗透率，后者低于100巴阻。其H2/CO2选择性为91，优于目前的膜技术。此外，皱巴巴的膜在恶劣条件下（- 20°C， 96%相对湿度）表现出稳定性，这是实际应用的关键要求。这项工作解决了长期存在的渗透率-选择性权衡，并建立了一个强大的，可扩展的平台，将二维材料集成到膜技术中，用于现实世界的应用。
