近年来，由于其独特的性能，包括环境友好性，可再生性和生物降解性，人们一直致力于开发木材衍生的功能性聚合物材料。因此，木材中主要成分（纤维素和木质素）的独特性引起了基础研究和实际应用的极大兴趣。本文综述了近年来利用高分子工程技术制备木质功能高分子材料的研究进展，包括木质功能高分子材料主要组分的基本结构和性能，利用木质功能高分子材料主要组分的设计原则，以及木质功能高分子材料的弹性体、水凝胶、气凝胶和纳米颗粒等。详细地，强调了木材构件的自然特性及其在材料制造中的重要作用。此外，利用受控/活性聚合、点击化学、动态键化学等，从分子设计的角度，结合它们的有序组装成不同的形态，对修饰进行了具体的讨论。木质高分子材料的功能主要集中在自修复和形状记忆能力、吸附、导电等方面。最后，提出了利用高分子工程技术制备木质高分子功能材料的主要挑战，以及开发绿色和可规模化木质高分子功能材料的潜在解决方案或方向。
In recent years, tremendous efforts have been dedicated to developing wood‐derived functional polymeric materials due to their distinctive properties, including environmental friendliness, renewability, and biodegradability. Thus, the uniqueness of the main components in wood (cellulose and lignin) has attracted enormous interest for both fundamental research and practical applications. Herein, the emerging field of wood‐derived functional polymeric materials fabricated by means of macromolecular engineering is reviewed, covering the basic structures and properties of the main components, the design principle to utilize these main components, and the resulting wood‐derived functional polymeric materials in terms of elastomers, hydrogels, aerogels, and nanoparticles. In detail, the natural features of wood components and their significant roles in the fabrication of materials are emphasized. Furthermore, the utilization of controlled/living polymerization, click chemistry, dynamic bonds chemistry, etc., for the modification is specifically discussed from the perspective of molecular design, together with their sequential assembly into different morphologies. The functionalities of wood‐derived polymeric materials are mainly focused on self‐healing and shape‐memory abilities, adsorption, conduction, etc. Finally, the main challenges of wood‐derived functional polymeric materials fabricated by macromolecular engineering are presented, as well as the potential solutions or directions to develop green and scalable wood‐derived functional polymeric materials.
