摘　　要：木质素是木质纤维素生物质的主要组成成分,是地球上存在的仅次于纤维素的最丰富的经济可再生型天然聚合物。这种结构复杂的芳香族聚合物是造纸、生物燃料等行业的低价值副产品,目前仍未被充分利用。由于木质素富含酚和脂肪族羟基等基团,易于进行化学改性,人们对于木质素基新材料等方向进行了越来越多的研究并取得了一定成果。本文综述了木质素的化学改性方法,并讨论了木质素及木质素衍生物作为表面活性剂在不同行业中的应用前景和趋势。Lignin is the main component of lignocellulosic biomass and is the most abundant economical and renewable natural polymer existing on earth after cellulose.This complex aromatic polymer is a low-value by-product of industries such as paper and biofuels,and is currently underutilized.Because lignin is rich in phenolic and aliphatic hydroxyl groups and is easy to be chemically modified,more and more researches have been carried out on new lignin-based materials and certain results have been achieved.This paper reviews the chemical modification methods of lignin,and discusses the application prospects and trends of lignin and lignin derivatives as surfactants in different industries.
