Abstract

Lignin, the only large-volume sustainable source of aromatic biopolymer in nature, is an attractive feedstock for the production of functional materials. However, considering its high reactivity, lignin is difficult to extract without avoiding uncontrolled degradation and condensation, which significantly impedes the upgrading of the extracted lignin into high-valued materials. Deep eutectic solvents (DES), as an emerging solvent choice, have driven innumerable advances in sustainable biorefinery, especially in lignin fractionation and valorization. Due to their property tunability and high lignin solubility, lignin modification with DES is an appealing approach to boost the extracted lignin’s reactivity and compatibility with polymers. This review systematically summarizes the latest progress of DES in lignin modification and further upgrading into functional materials.

用创新的DES技术释放木质素的潜力

木质素是自然界中唯一大量可持续的芳香族生物聚合物来源，是生产功能材料的有吸引力的原料。然而，由于木质素的高反应性，在不避免不受控制的降解和缩合的情况下很难提取木质素，这严重阻碍了提取的木质素向高价值材料的升级。深度共晶溶剂(DES)作为一种新兴的溶剂选择，推动了可持续生物炼制的无数进步，特别是在木质素分馏和增值方面。由于其可调性和高木质素溶解度，用DES改性木质素是提高提取木质素的反应性和与聚合物的相容性的一种有吸引力的方法。本文系统综述了DES在木质素改性及进一步升级为功能材料方面的最新进展。
