| 摘 要： | 利用对甲苯磺酸/氯化胆碱（TA/CC）制备的低共熔溶剂（DES）处理碱木质素，提取得到富含酚类的木质素精油，将其添加到杨木浆中，制备了抗菌纸。结果表明，DES处理后得到的木质素精油中含有大量酚羟基，制得的抗菌纸对大肠杆菌的抗菌率约100%，在食品包装用纸、医疗用纸等领域具有较大的应用潜力。

| Abstract: | Deep eutectic solvent （DES）-pretreated alkaline lignin was prepared using p-toluenesulfonic acid and choline chloride（TA/CC） and resulted in a phenol-rich lignin essential oil extract. It was subsequently incorporated into poplar pulp to produce antibacterial paper. The results demonstrated that the pretreatment of lignin with DES led to the generation of a significant number of phenolic hydroxyl groups， and the prepared antibacterial paper exhibited an inhibition rate of approximately 100% against Escherichia coli， suggesting significant potential applications in fields such as food packaging paper and medical paper. |
