Two different organosolv lignins (OSLs), that is, wheat straw and corn stover OSLs, were chemically and enzymatically functionalized. Functional groups were attached via the formation of stable ether bonds exploiting the reactivity of free phenolic OH groups along the lignin backbone. The functional groups introduced a range from compact charged and chargeable building blocks for the generation of surface-active lignins to oligomeric and polymeric species used in lignin block-copolymer productions. Combination of selected functions led to novel charged or chargeable polymeric lignin-based materials. Products could be realized with different degrees of technical loadings in terms of introduced functional groups.
两种不同的有机溶剂木质素（OSL），即麦秸和玉米秸秆OSL，进行了化学和酶功能化处理。利用木质素主链上游离酚羟基的反应性，通过形成稳定的醚键连接官能团。引入的官能团范围从用于生成表面活性木质素的致密带电和可充电结构单元到用于木质素嵌段共聚物生产的低聚物和聚合物。选定功能的组合产生了新型的带电或可充电的基于聚合物木质素的材料。就引入的官能团而言，可以实现具有不同技术负载程度的产品。
