摘要:

木质素是自然界储量丰富的可再生天然酚类高分子,可替代传统化石资源应用于聚合物材料合成。木质素分子结构中的大分子刚性骨架可赋予材料独特的力学性能和热稳定性。但木质素化学组成和分子结构复杂、反应活性低,限制了在聚合物材料领域的应用。化学降解是一种高效、高选择性且应用广泛的降解方法,经化学降解处理得到的木质素低聚物具有活性官能团多、反应活性高、溶解性好等优点,有利于拓展木质素在聚合物材料领域的高附加值应用。重点综述了近年来国内外有关木质素化学降解及其降解产物应用于聚合物材料的研究进展。

Abstract:

As a kind of abundant renewable phenolic structure polymer, lignin could replace traditional fossil resources to be used in synthetizing polymer materials. Especially, its rigid aromatic macromolecular structure could give materials good thermal stability and mechanical performance. However, the complex chemical composition and molecular structure, lower reactivity of lignin limited its application. Chemical degradation had advantages of high efficiency, high selectivity and could be used widely. Compared to lignin, oligomers derived from lignin chemical degradation had more reactive functional groups, higher reactivity and better solubility, which would be beneficial to expanding the high value-added applications of lignin in the field of polymer materials. The current research progress on the chemical degradation of lignin and its products applications in polymer materials were mainly reviewed.

Key words: lignin, chemical degradation, oligomer, reactivity, polymer material
