本研究报道了通过酶催化和可逆加成-断裂链转移聚合（RAFT）之间的组合对纤维素材料进行改性的生态友好的接枝聚合方法。采用辣根过氧化物酶（HRP）引发RAFT聚合法，在纤维素滤纸上聚合聚丙烯酰胺（PAM）。接枝率、转化率和准一级反应动力学的研究结果表明，聚丙烯酰胺在滤纸上的接枝聚合符合RAFT反应规律。衰减全反射（ATR-FTIR）、元素分析和X射线光电子能谱（XPS）的结果证实了PAM接枝滤纸中PAM的存在。水接触角和热重分析（TG）的结果表明，处理后的滤纸的润湿性能和热性能的变化，分别。本工作为纤维素材料的接枝聚合提供了一种新的环保途径。
This study reports on eco-friendly graft polymerization approach for the modification of a cellulosic material via combination between enzymatic catalysis and reversible addition-fragmentation chain transfer polymerization (RAFT). Polyacrylamide (PAM) was polymerized on a cellulosic filter paper via horseradish peroxidase (HRP)-initiated RAFT polymerization. The results of grafting ratio, conversion, and pseudo-first-order kinetics were proved that the PAM graft polymerization on the filter paper followed RAFT rules. The results of Attenuated total reflection (ATR-FTIR), elemental analysis, and X-ray photoelectron spectroscopy (XPS) confirmed the presence of PAM in PAM-grafted filter paper. The results of water contact angle and Thermogravimetric analysis (TG) evidenced the change in the wetting properties and thermal performance, respectively of the treated filter paper. This work provides a new environmentally approach to graft polymerization on cellulosic materials.
