In this study, cupric oxide (CuO) nanoparticles were prepared using sonochemical method. The prepared nanoparticles were studied using X-ray diffraction (XRD) pattern, Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and transmission electron microscopy (TEM) methods. The colloidal chitosan (CS) solution was prepared using ultrasound irradiation method and simultaneously mixed with CuO nanoparticles. The coatings of colloidal solution with and without CuO nanoparticles were studied through TEM images. The cotton fabrics were separately soaked in the prepared nanoparticle-containing (hybrid) solutions by sonication method followed by pad-dry-cure method. The structural, functional, and morphological analyses of the coated and uncoated fabrics were performed using XRD, FTIR-attenuated total reflectance, and SEM analyses, respectively. The hybrid-coated cotton fabrics showed better antibacterial activity against Staphylococcus aureus and Escherichia coli. The bioactivity performance of the coated fabrics was in the order of CuO-coated fabric > CS-coated fabric.
在本研究中，采用声化学方法制备了氧化铜（CuO）纳米颗粒。使用X射线衍射（XRD）图谱、傅里叶变换红外（FTIR）光谱、扫描电子显微镜（SEM）和透射电子显微镜（TEM）方法对制备的纳米颗粒进行了研究。采用超声辐照法制备了胶体壳聚糖（CS）溶液，并同时与CuO纳米颗粒混合。通过TEM图像研究了含和不含CuO纳米颗粒的胶体溶液涂层。将棉织物分别通过超声处理方法浸泡在制备的含纳米颗粒（混合）溶液中，然后采用轧染-烘干-焙烘法处理。分别使用XRD、FTIR衰减全反射和SEM分析对涂层和未涂层织物进行了结构、功能和形态分析。混合涂层棉织物对金黄色葡萄球菌和大肠杆菌表现出更好的抗菌活性。涂层织物的生物活性性能顺序为：CuO涂层织物＞CS涂层织物。
