摘要

以氯化1-烯丙基-3-甲基咪唑（[AMIM]Cl）离子液体为溶剂，采用原子转移自由基聚合法（ATRP）在微晶纤维素上接枝功能单体N-羟甲基丙烯酰胺，制备了卤胺化合物中间体，应用卤化法将接枝共聚物中的N-H转化为N-Cl键获得具有抗菌性的共聚物材料，并对其抗菌性能进行研究。通过FT-IR、1H NMR、SEM以及抗菌测试等分析手段表征分析了聚合物的结构、表面形貌和抗菌性能等。结果表明该工艺合成了纤维素接枝N-羟甲基丙烯酰胺共聚物，接枝后表面明显变得粗糙，有利于材料与细菌的接触进而充分发挥其抗菌性能，制备的材料对金黄色葡萄球菌和大肠杆菌均表现出良好抗菌性能，在抗菌材料领域具有较好的应用前景。

Abstract

Functional monomer N-methylolacrylamide was grafted onto microcrystalline cellulose to prepare the intermediates MCC-g-PHAM by atom transfer radical polymerization (ATRP) in ionic liquid 1-allyl-3-methyl-imidazole chloride. Halogenation was used to convert N-H in graft copolymer into N-Cl bond to obtain antibacterial copolymer

and its antibacterial properties were studied. The obtained polymer structure

surface morphology and antibacterial properties were characterized by FT-IR

1H NMR

SEM and antibacterial test. The result showed that the cellulose graft copolymer has been successfully synthesized and the surface after grafting became noticeably rougher. Therefore

the contact between the material and the bacteria is facilitated and the antibacterial performance is fully exerted. The material exhibits perfect antibacterial performance against Staphylococcus aureus and Escherichia coli. Thus the obtained material presents a better application prospect on the antibacterial field.
