摘　　要：木质素基导电水凝胶由木质素及其衍生物交联制备而成。作为制浆造纸工业的副产物,木质素来源广泛,且其本身具有的官能团能够赋予水凝胶可调节的功能特性。通过不同方式制备木质素基导电水凝胶,可以进一步提高木质素的附加值并拓宽其应用范围。本文基于木质素的种类、基本结构单元、官能团,按照不同分类方式归纳了木质素基导电水凝胶的制备方法,并展望了木质素基水凝胶电解质在低温下仍能保持良好电化学性能的超级电容器中的应用前景。Lignin-based conductive hydrogels are prepared via cross-linking by lignin and its derivatives.As a by-product of pulp and paper industry,lignin come from a wide range of sources and their own functional groups are able to give hydrogels adjustable functional properties.Through different preparation methods,the added value of lignin can be further increased and the application range can be expanded.In this paper,based on the types,structural units and functional groups of lignin,the preparation methods of lignin-based conductive hydrogels were summarized according to different classification methods,and the research prospect of lignin-based hydrogel electrolytes used in supercapacitors with the good electrochemical performance at low temperatures was proposed.
