As one of the most abundant and versatile natural materials on Earth, recently wood has attracted tremendous attention from scientists and engineers due to its outstanding advantages, including hierarchically porous microstructure, high mechanical strength, environmental friendliness, renewability, and biodegradability. Wood’s hierarchically porous structure and chemical components (e.g., cellulose, hemicelluloses, and lignin) enable its mechanical, ionic, optical, and thermal properties to be tuned via physical, chemical, and/or thermal modifications. Among these various approaches, the chemical delignification of bulk wood is the most fascinating, in which the majority of lignin and hemicelluloses is removed while leaving the cellulose intact, maintaining wood’s physical integrity and hierarchical structure. This delignified structure is unique, composed of hollow, aligned channels made up of cellulose microfibrils, and particularly attractive given its origin from a sustainable and renewable resource. As a result, delignified wood has attracted increasing attention for applications that go far beyond traditional wood utilization, such as lightweight yet strong structural materials, energy storage and conversion, environmental remediation, flexible electronics, and bioengineering.

可持续应用的原位木材脱木素

木材作为地球上最丰富、用途最广的天然材料之一，近年来以其层次多孔的微观结构、高机械强度、环境友好、可再生和可生物降解等突出优点引起了科学家和工程师的极大关注。木材的分级多孔结构和化学成分（例如纤维素、半纤维素和木质素）使其机械、离子、光学和热特性能够通过物理、化学和/或热改性进行调节。在这些不同的方法中，散装木材的化学脱木素是最吸引人的，其中大部分木质素和半纤维素被去除，同时保持纤维素完整，保持木材的物理完整性和层次结构。这种去木质素的结构是独一无二的，由纤维素微纤维组成的空心对齐通道组成，鉴于其源自可持续和可再生资源，因此特别有吸引力。因此，脱木素木材在远远超出传统木材利用的应用领域引起了越来越多的关注，例如轻质而坚固的结构材料、能量存储和转换、环境修复、柔性电子产品和生物工程。
