摘要:不同原料和制浆工艺所得的工业木质素的结构与基团差别很大,其反应活性也较原本木质素要低。因此,可以通过活化改性改善其物化性能,以提高与其他聚合物的相容性,进而制备出化学性能优良的木质素基复合材料。本文综述了工业木质素的主要活化改性方法,对改性木质素在紫外防护、抗菌和抗氧化、吸附、生物医学和农药缓释等木质素基复合材料方面的应用进展做了详细介绍。
Abstract:Lignin-based composites materials have become a focus in the research field of high value utilization of biomass in recent years. However, the structure and functional groups of lignin separated in the industrial process are greatly changed, leading to the industrial lignin has a lower reactivity and difficult to be used efficiently.Therefore, it is of great significance to improve the physical and chemical properties of industrial lignin and improve its compatibility with other polymers through activation modification methods, and only by which the lignin-based composite materials with excellent chemical properties could be prepared. In this paper, the main activation modification methods of industrial lignin were firstly reviewed, and then the research progress of the application of modified lignin in lignin-based functional materials such as ultraviolet protection materials, antibacterial and antioxidant materials, adsorption materials, biomedical materials and pesticide sustained release materials were introduced in detail.
