Water contaminated with microorganisms causes numerous diseases and is a major concern for public health. In search of a simple material which can provide clean water free from pathogens, nanofibers of poly(4-chloro-3-methylphenyl methacrylate, abbreviated as CMPMA, and nano Ag-doped poly(CMPMA) composite nanofibers were used to decontaminate water from microorganisms such as Escherichia coli and Bacillus subtilis. Nanofibers were prepared by electrospinning. X-ray diffraction (XRD) and transmission electron microscopy (TEM) provide the diameters of the Ag nanoparticles which are in the range 18-21 and 13-18 nm. The diameter of the poly(CMPMA) and nano Ag-doped poly(CMPMA) composite nanofiber is seen to vary between 400 and 700 nm with the change of the processing parameters. Optimum parameters for uniform nanofibers have been obtained. The morphology of the fibers is derived from scanning electron microscopy (SEM). The superiority of the nano Ag-doped poly(CMPMA) composite nanofiber was established.
被微生物污染的水会引发多种疾病，是公共卫生领域的一大担忧。为了寻找一种能够提供无病原体清洁水的简单材料，聚（4-氯-3-甲基苯基甲基丙烯酸酯，简称为CMPMA）纳米纤维以及纳米银掺杂的聚（CMPMA）复合纳米纤维被用于净化含有大肠杆菌和枯草芽孢杆菌等微生物的水。纳米纤维通过静电纺丝制备。X射线衍射（XRD）和透射电子显微镜（TEM）给出了银纳米颗粒的直径，其范围在18 - 21纳米和13 - 18纳米之间。聚（CMPMA）和纳米银掺杂的聚（CMPMA）复合纳米纤维的直径随着加工参数的变化在400到700纳米之间变化。已获得制备均匀纳米纤维的最佳参数。纤维的形态通过扫描电子显微镜（SEM）得出。纳米银掺杂的聚（CMPMA）复合纳米纤维的优势得以确立。
