采用自由基聚合法制备了二甲基二烯丙基氯化铵-烯丙基缩水甘油酯醚-甲基丙烯酸聚合物，简称为P（DMDAAC-AGE-MAA）。将聚合物与纳米zno在不同pH下混合，得到P(DMDAAC-AGE-MAA)/纳米zno复合材料。采用傅里叶变换红外（FT-IR）、x射线衍射（XRD）和透射电镜（TEM）对P(DMDAAC-AGE-MAA)/纳米zno复合材料进行了表征。结果表明，复合材料中存在纳米氧化锌，聚合物链不能包封纳米氧化锌。纳米zno与聚合物的络合作用改变了聚合物的晶体结构。当聚合物的pH为2.6和3.0时，P(DMDAAC-AGE-MAA)/纳米zno复合材料的形貌为核壳结构和长条形结构。将复合材料加载到棉织物上，利用扫描电镜（SEM）对织物表面形貌进行了表征。研究了P（DMDAAC-AGE-MAA）聚合物和P(DMDAAC-AGE-MAA)/纳米zno复合材料处理棉及洗涤5次（相当于家庭洗涤25次）处理棉对金黄色葡萄球菌(S。金黄色念珠菌（ATCC25923）和真菌白色念珠菌(C。白色的,ATCC10231)。P(DMDAAC-AGE-MAA)/纳米zno处理棉的抑菌活性高于P（DMDAAC-AGE-MAA）处理棉。
The polymer dimethyl diallyl ammonium chloride-allyl glycidyl ether-methacrylic shortened as P(DMDAAC-AGE-MAA) was prepared via free radical polymerization. P(DMDAAC-AGE-MAA)/nano-ZnO composites were obtained after mixing the polymer under different pH with nano-ZnO. P(DMDAAC-AGE-MAA)/nano-ZnO composites were characterized by Fourier transformation infrared (FT-IR), X-ray diffraction (XRD) and transmission electron microscopy (TEM). The results showed that nano-ZnO existed among the composites, and the polymer chain did not encapsulate nano-ZnO. The crystal structure of polymer changed because of the complexation of the polymer with nano-ZnO. The morphologies of P(DMDAAC-AGE-MAA)/nano-ZnO composites were core–shell and long strip structure when the pH of polymer was 2.6 and 3.0. After composite materials were loaded onto cotton fabrics, the surface morphology of the fabrics was characterized by scanning electron microscope (SEM). The antibacterial properties of P(DMDAAC-AGE-MAA) polymer and P(DMDAAC-AGE-MAA)/nano-ZnO composites treated cottons and treated cottons after being washed 5 times (equivalent of household washing 25 times) were tested against the bacteriumStaphylococcus aureus(S.aureus, ATCC25923) and the fungusCandida albicans(C.albicans, ATCC10231). P(DMDAAC-AGE-MAA)/nano-ZnO treated cottons had higher antibacterial activities than P(DMDAAC-AGE-MAA) treated cottons.
