摘要
木质素是一种储量丰富、环境友好的多酚类生物聚合物,可作为天然抗氧化剂使用。同时,木质素具有光稳定性好、抗紫外、可生物降解等优势,如何更好地开发和利用其抗氧化功能引起了研究者的广泛关注。首先,该文重点回顾了国内外在木质素抗氧化构效关系方面的研究进展,归纳总结了木质素结构对其抗氧化能力的影响规律及其作用机制,并讨论了目前木质素抗氧化构效关系研究面临的主要问题;其次,从分级纯化、纳米化和化学改性3种技术方法出发,介绍了近年来研究人员在强化木质素抗氧化能力方面做出的努力;最后,基于木质素在防晒护肤品、高分子功能复合材料和医药材料中的应用现状,评述了木质素抗氧化特性对紫外防护、热氧稳定性、抑菌等性能的贡献,为今后木质素基功能材料的制备及应用提供一定参考。
Lignin,an abundant and environment-friendly polyphenol polymer,can be used as a natural antioxidant.Meanwhile,due to its advantages of good light stability,UV resistance and biodegradability,how to better develop and utilize the antioxidant function of lignin has attracted extensive attention from researchers.Herein,the recent advances on the structure-antioxidant activity relationship of lignin,the influence and working mechanism of its structure on antioxidant performance,and the existing problem were firstly summarized and discussed.Subsequently,the work done by researchers in improving the antioxidant activity of lignin was introduced in terms of fractional purification,nano modification and chemical modification.Finally,the contribution of antioxidant property of lignin to the anti-UV ability,thermal oxygen stability and bacteriostatic activity was discussed on the basis of its application in sunscreen,polymer functional composites and medical materials,which could provide a reference in preparation and application of lignin-based functional materials in the future.
