中文摘要:

      木质生物质作为储量最丰富的生物质资源，因具有可再生性、良好的生物相容性和生物可降解性等特点而在众多研究领域备受瞩目。木质生物质通过改性构建的黏附水凝胶除具有上述特性外，还被赋予了高强度、高韧性、抗菌或抗紫外线等特殊功能，使其在生物医学、传感等领域具有广泛的应用前景。本文围绕木质生物质基黏附水凝胶的网络构筑方式，从共价键、非共价键和动态可逆键三方面介绍了不同木质生物质基黏附水凝胶的特点与形成机理，并综述了其在伤口修复、智能可穿戴设备和食品等领域的最新应用进展。最后，对木质生物质基黏附水凝胶的发展前景和所面临的挑战进行了展望。

Abstract:

      As the most abundant biomass resource， woody biomass has the characteristics of renewability， good biocompatibility and biodegradability， and has attracted much attention in many research fields. In addition to the above properties， adhesive hydrogels constructed by modification of woody biomass are endowed with special functions such as high strength， high toughness， antibacterial or anti-ultraviolet， etc. so that it has a wide range of application prospects in biomedicine， sensor and other fields. In this paper， around the structural construction methods of adhesive hydrogels based on wood biomass， the characteristics and formation mechanisms of different adhesive hydrogels based on wood biomass were introduced from the three aspects of covalent bond， non-covalent bond and dynamic reversible bond， and the latest progress of their applications in wound repair， smart wearable devices and food were reviewed. Finally， the challenges faced by lignocellulosic bio-based adhesive hydrogels were prospected.
