木质素基抗氧剂在聚合物制品中应用研究进展
Advances in the synthesis and application of lignin-based bio-antioxidants
综述了木质素的结构特性、功能化改性策略及其在塑料、薄膜和橡胶领域的应用进展。结构复杂且反应活性低的木质素通过功能化改性,包括胺化、羧基化、酯化以及羟基化引入活性官能团,实现定向调控其抗氧化活性及与聚合物基体的相容性,用作生物基抗氧化剂能显著提升塑料、薄膜以及橡胶的抗氧化老化性能。木质素的高值化利用推动了聚合物行业向绿色化转型,为生物质资源循环利用和“双碳”目标实现提供了创新路径。未来研究需进一步揭示长效抗氧化机制,开发低成本改性工艺,实现木质素的生产和改性过程标准化,以推动木质素基高分子材料工业化应用进程。
The structural attributes of lignin,functional modification methodologies,and its application advancements in plastics,films,and rubber are comprehensively reviewed here.The lignin with complex structure and relatively low reactivity can be functionally modified by introducing active functional groups such as amination,carboxylation,esterification and hydroxylation to achieve the targeted regulation of its antioxidant activity and compatibility with polymer matrix.It can significantly enhance the antioxidant aging performance of plastics,films and rubbers.The high-value utilization of lignin promotes the green transformation of the polymer industry and provides an innovative path for the recycling of biomass resources and the realization of the “dual carbon” goals.Future research needs to further reveal the long-term antioxidant mechanism,develop low-cost modification methodologies,achieve standardized production and modification process of lignin,and promote the industrial application process of lignin-based polymer materials.
