摘要:木质素的化学改性方法主要分为3类，包括木质素裂解、合成新的化学活性位点和羟基功能化，这些方法为木质素在聚合物中的应用提供了新的思路。本文总结了木质素作为农用材料在化肥、植物生长调节剂、农药方面的应用；作为生物医学材料在组织工程和DNA传递方面的应用；以及作为智能材料在生物传感和形状可编程材料领域应用的研究进展。

Abstract:The chemical modification methods of lignin are mainly divided into three categories， including lignin depolymerization， synthesis of new chemically active sites， and functionalization of hydroxyl groups. These methods provide new ideas for the application of lignin in polymers. The application and research progress of lignin as agricultural material in fertilizer， plant growth regulator， and pesticide； as biomedical materials in tissue engineering and DNA delivery applications； as smart materials in biosensors and shape programmable materials were summarized in this paper.
