Atomically thin 2D materials, such as graphene, hexagonal boron‐nitride, and others, offer new possibilities for ultrathin barrier and membrane applications. While the impermeability of pristine 2D materials to gas molecules, such as He, allows the realization of the thinnest physical barrier, nanoscale vacancy defects in the 2D material lattice manifest as nanopores in an atomically thin membrane. Such nanoporous atomically thin membranes (NATMs) present potential for enabling ultrahigh permeance and selectivity in a wide range of novel separation processes. Herein, the transport properties observed in NATMs are described and recent experimental progress achieved in their fabrication is summarized. Some of the challenges in NATM scale‐up for practical applications are highlighted and several opportunities are identified, including the possibility of blending traditional membrane‐processing approaches. Finally, a technological roadmap is presented with a contextual discussion for NATMs to progress from research to applications.

二维材料中的原子薄膜的最新技术和未来前景

原子薄的2D材料，例如石墨烯，六方氮化硼等，为超薄阻隔和膜应用提供了新的可能性。原始2D材料对气体分子（例如He）的不渗透性允许实现最薄的物理屏障，而2D材料晶格中的纳米级空位缺陷表现为原子薄膜中的纳米孔。此类纳米多孔原子薄膜（NATM）具有在各种新型分离方法中实现超高渗透性和选择性的潜力。在此，描述了在NATM中观察到的传输性质，并总结了在其制备中获得的最新实验进展。强调了NATM在实际应用中扩大规模时所面临的一些挑战，并确定了一些机会，包括混合传统膜处理方法的可能性。最后，提出了技术路线图，并通过上下文讨论了NATM从研究到应用的发展。
