摘要 以二甲基二烯丙基氯化铵(DMDAAC)、甲基丙烯酸(MAA)、烯丙基缩水甘油醚(AGE)、纳米ZnO为原料,通过原位法制备了聚二甲基二烯丙基氯化铵-甲基丙烯酸-烯丙基缩水甘油醚/纳米ZnO(PDMDAAC-AGE-MAA/纳米ZnO)复合材料,考察了纳米ZnO用量对复合材料性能的影响,通过FT-IR、XRD和TEM对其结构进行了表征,将其应用于棉织物整理中。结果表明:当纳米ZnO为0.8%时,PDMDAAC-AGE-MAA/纳米ZnO复合材料的稳定性最佳;复合材料中存在环氧基团以及纳米氧化锌的特征吸收峰,纳米ZnO在复合材料中具有良好的分散性;将其整理织物后,与原布相比,经10次标准洗涤织物对金黄色葡萄球菌和大肠杆菌的抗菌率高达80%以上,对白色念珠菌的抗菌性可达75%以上,具有良好的耐洗牢度;经过整理后的织物断裂强力无影响。

Abstract:The PDMDAAC-AGE-MAA/nano-ZnO composite was prepared by dimethyl diallyl ammonium chloride (DMDAAC), allyl glycidyl ether (AGE), methylacrylic acid (MAA) and nano-ZnO via in-situ polymerization. The effect of the dosage of nano-ZnO on the performance of PDMDAAC-AGE-MAA/nano-ZnO composite was investigated, and the composite was characterized by FT-IR, XRD and TEM. Then cotton fabric was treated with PDMDAAC-AGE-MAA/nano-ZnO composite. The results show that when the dosage of nano-ZnO is 0.8%, the stability of PDMDAAC-AGE-MAA/nano-ZnO composite is the best; The characteristic absorption peaks of the epoxy groups and nano-ZnO exist in the PDMDAAC-AGE-MAA/nano-ZnO composite, Nano-ZnO is good dispersion in composite; Compared with the control cotton sample, the cotton treated with the PDMDAAC-AGE-MAA/nano-ZnO composite after 10 times of standard washing shows the precent reduction of antibacterial properties against Escherichia coli(E.coli) and Staphylococcus aureus(S.aureus) is above 80%, and the percent reduction of antibacterial properties against Candida albicans(C.albicans) is above 75%, because of the antibacterial properties of the synergistic effect by nano-ZnO and N+ in the composite.The PDMDAAC-AGE-MAA/nano-ZnO composite is coated on the surface of treated cotton fibers. After standard washing, the elements of Zn and N still remain in the treated cotton samples, the cotton treats with PDMDAAC-AGE-MAA/nano-ZnO composite possesses good washing fastness. Compared with the untreated cotton,the cotton treated with PDMDAAC-AGE-MAA/nano-ZnO composite has no effect on the breaking strength.
