摘要
木质素作为可再生自然资源,具有多种高附加值的功能特性,将其与可生物降解高分子聚合物复合是其转化利用的重要途径之一。然而,木质素的异质性限制了其在复合材料中的开发和利用,采取针对性的策略和方法生产高附加值的木质素基可生物降解复合材料至关重要。本文主要阐述了高性能木质素/聚己二酸/对苯二甲酸丁二酯(PBAT)复合材料的不同制备策略,如添加增容剂、木质素的溶剂分级、纳米化和化学改性等,进一步总结了该复合材料在紫外屏蔽、水蒸气/氧气阻隔和抗菌等方面的潜在应用,并对木质素/PBAT复合材料所面临的挑战和未来发展方向进行总结和展望。
Lignin as a renewable natural resource,has a variety of high value-added functional properties,and the combination of lignin with bio⁃degradable polymers is one of the important ways for its conversion and utilization.However,the heterogeneity of lignin restricted its development and utilization in composites,it was of significance to adopt tailored strategies and methods to produce high value-added lignin-based biodegrad⁃able composites.The different fabrication strategies of high-performance lignin/poly-(butylene adipate-co-tere phthalate)(PBAT)composites were mainly described in this paper,such as adding compatibilizers,solvent fractionation,micro-nano crystallization and chemical modification of lig⁃nin,etc.The potential applications of the composites in UV shielding,water vapor/oxidation barrier and antibacterial and so on were further sum⁃marized.The challenge and future development direction of lignin/PBAT composites were summarized and prospected.
