Cellulose, as the most abundant natural polymer on Earth, has long captured researchers' attention due to its high strength and modulus. Nevertheless, transferring its exceptional mechanical properties to macroscopic 2D and 3D materials poses numerous challenges. This review provides an overview of the research progress in the development of strong cellulose-based materials using both the “bottom-up” and “top-down” approaches. In the “bottom-up” strategy, various forms of regenerated cellulose-based materials and nanocellulose-based high-strength materials assembled by different methods are discussed. Under the “top-down” approach, the focus is on the development of reinforced cellulose-based materials derived from wood, bamboo, rattan and straw. Furthermore, a brief overview of the potential applications fordifferent types of strong cellulose-based materials is given, followed by a concise discussion on future directions.

针对强纤维素基材料的“自下而上”和“自上而下”策略

纤维素作为地球上最丰富的天然聚合物，由于其高强度和模量长期以来引起了研究人员的关注。然而，将其卓越的机械性能转移到宏观 2D 和 3D 材料面临着许多挑战。本综述概述了使用“自下而上”和“自上而下”方法开发强纤维素基材料的研究进展。在“自下而上”的策略中，讨论了通过不同方法组装的各种形式的再生纤维素基材料和纳米纤维素基高强度材料。在“自上而下”的方法下，重点是开发源自木、竹、藤和稻草的增强纤维素基材料。此外，还简要概述了不同类型强纤维素基材料的潜在应用，然后对未来方向进行了简要讨论。
