摘　　要：木质素具有一定的疏水性,且成本低、可再生、对环境友好。在木质素结构中引入亲水性基团,能够提高木质素的溶解性和表面活性,形成木质素两亲聚合物,以进一步制备木质素基表面活性剂和Pickering乳液乳化剂。本文综述了木质素两亲聚合物的研究进展,重点介绍了木质素基表面活性剂的种类和影响因素,并讨论了利用缩醛保护的木质素制备两亲聚合物的方法机理及应用领域。此外,本文总结了木质素基乳化剂稳定Pickering乳液的研究现状,简述了将木质素转化为高值产品的机遇与挑战。Lignin has certain hydrophobicity,and is low cost,renewable and environmentally friendly.Introduction of hydrophilic groups to lignin structure can improve its solubility and surface activity,form lignin amphiphilic polymers,and further prepare lignin-based surfactants and stabilizers of Pickering emulsion.The paper reviewed the research progress of lignin-based amphiphilic polymers,and focused on the types,and influencing factors of lignin-based surfactants.The method,mechanism and application fields of amphiphilic polymers preparing from lignin protected by acetalization was discussed.In addition,the research status of Pickering emulsion stabilized by lignin-based emulsifier was summarized.Finally,the opportunities and challenges of converting lignin into value-added products were briefly described.
