摘　　要：随着石油资源的逐渐枯竭,生物质基阻隔包装材料作为传统石油基塑料包装的绿色替代品受到越来越多重视。木质素作为自然界中第二丰富的天然高分子聚合物,也是唯一富含重复苯环结构单元的可再生资源,具有生物可降解性、生物相容性和出色的加工性等优势。现阶段,大部分木质素仍作为工业副产物被焚烧处理,其高值化利用程度较低。虽然木质素独特的化学结构和耐水、耐溶剂、抗老化、抗紫外等功能特性,使其在制备生物基阻隔材料方面具有巨大潜力。但木质素的结构、木质素基阻隔材料的多重阻隔性能、构效关系及应用场景仍需深入思考。鉴于此,本文对木质素基功能材料在阻隔包装纸中的应用研究进展进行了系统总结和全面评述。首先,简述了木质素的结构和来源。其次,详细概括了木质素基功能材料在阻隔包装纸上的应用现状,重点介绍了木质素基功能材料在包装纸阻隔水、气体、油脂、紫外线及阻燃方面的应用进展。最后,探讨了木质素基功能材料在阻隔包装纸应用中面临的主要挑战和未来的发展方向。本文将为木质素基功能材料在制备具有单一或多重阻隔性能包装纸的应用研究领域提供理论参考,对工业化生产木质素基高附加值产品具有实际意义。With the gradual depletion of petroleum resources,bio-based barrier packaging materials have garnered growing attention as an eco-friendly alternative to conventional petroleum-based plastic packaging.Lignin,the second most abundant natural polymer and the only renewable resource rich in repetitive benzene ring structural units,possesses biodegradability,biocompatibility and excellent processability.Currently,the majority of lignin is still disposed of through incineration as industrial by-products,resulting in limited utilization and low added value.Due to its unique chemical structure,water resistance,solvent resistance,aging resistance,and UV resistance,lignin exhibits significant potential in the development of bio-based barrier materials.However,further consideration is required regarding the structural characteristics of lignin,its multifaceted barrier properties in material applications,the establishment of structure-property relationships,and exploration of diverse application scenarios.Therefore,the present review provides a systematic and comprehensive review of the application of lignin-based functional materials in barrier packaging paper.Firstly,the structure and origin of lignin are briefly elucidated.A comprehensive overview of the current status of the application of lignin-based functional materials in barrier packaging papers is then provided,with particular emphasis on the advances in the use of lignin-based functional materials for water,gas,oil,ultraviolet radiation and flame retardancy properties in packaging paper.Finally,the primary challenges and future prospects for the development of lignin-based functional materials in barrier packaging paper applications are discussed.This review will provide a theoretical foundation for the utilization of lignin-based functional materials in the production of paper with single or multiple barrier properties,thereby providing practical significance for the industrial-scale manufacturing of value-added products derived from lignin.
