摘要
以甲基丙烯酰氧乙基三甲基氯化铵作为单体,加入丙烯酸甲酯,以过硫酸钾为催化剂,水溶液聚合制备含季铵盐共聚物,并使该共聚物接枝到棉织物表面,制得新型的聚季铵盐抗菌棉织物。采用核磁共振氢谱、傅里叶变换红外光谱、扫描电子显微等分析手段对改性的抗菌棉织物进行性能表征,研究棉织物表面元素组成以及形貌特征,分析改性棉织物的抗菌性能。结果表明,甲基丙烯酰氧乙基三甲基氯化铵与丙烯酸甲酯的摩尔比为100:1时,制备的聚季铵盐抗菌棉织物具有优异的抗菌性能,对大肠杆菌和金黄色葡萄球菌的抑菌率分别为92.06%和92.33%。
Antibacterial polymer DMC-MA was prepared by aqueous solution polymerization with methacryloyloxyethyl trimethylammonium chloride as monomer,methyl acrylateand potassium persulfate as catalyst.The copolymer was grafted onto the surface of cotton fabric and a new type of antibacterial cotton fabric was prepared.1H-NMR,FTIR and SEM were used to test.The surface element composition and morphological characteristics of the cotton fabric were studied,and the antibacterial properties of the modified cotton fabric were analyzed.The results show that when the molar ratio of DMC to MA was 100:1,the prepared polyquaternary ammonium salt antibacterial cotton fabric had excellent antibacterial properties,and the antibacterial rates against Escherichia coli and Staphylococcus aureus were 92.06%and 92.33%respectively.
