木质素作为仅次于纤维素的第二大天然聚合物，由于其可再生性、安全性和生物降解性而受到广泛关注。研究现在集中在开发新的木质素应用，以取代石油基化学品。不幸的是，木质素具有几个固有的问题，例如差的水溶性和附聚的倾向。而木质素经过化学改性后，可以通过引入新的官能团而获得新的功能。例如，两亲性木质素是可溶于水和有机溶剂两者的聚合物。两亲性木质素聚合物根据其分子结构中所含的离子可分为阴离子型、阳离子型和阴离子-阳离子型两性木质素基聚合物。两亲性木质素聚合物在各种工业领域中也具有广泛的应用，并且可以用作润湿剂、洗涤剂、控释肥料、吸附剂和乳化剂。本文综述了近10年来木质素两亲聚合物的合成及应用研究进展，为木质素高附加值、高性能的利用提供理论参考。
As the second most abundant natural polymer after cellulose, lignin has received considerable attention recently due to its reproducibility, safety, and biodegradability. Studies are now focusing on the development of new lignin applications to replace petroleum-based chemicals. Unfortunately, lignin has several inherent problems, such as poor water solubility and a tendency to agglomerate. However, after chemical modification, lignin can gain new functions through the introduction of new functional groups. For example, amphiphilic lignin is a polymer that is soluble in both water and organic solvents. Amphiphilic lignin polymers can be divided into anionic, cationic, and anionic-cationic amphoteric lignin-based polymers, according to the ions contained in their molecular structure. Amphiphilic lignin polymers also have a wide range of applications in various industrial fields and can be used as wetting agents, detergents, controlled release fertilizers, adsorbents, and emulsifiers. Thus, this article reviews research progress on the synthesis and applications of amphiphilic lignin-derived polymers over the past 10 years, providing a theoretical reference for the utilization of high-added-value and high-performance lignin.
