Various shapes of ZnO; multi-petals, rod and spherical were prepared and then applied on cotton fabric for UV-blocking. The ZnO particles were investigated by XRD and SEM. The mixture solution of ZnO with polyvinyl alcohol was applied onto cotton fabrics via electrospinning. The characteristics of the fabric coating were investigated by SEM, XRD, Tensile testing and Atomic absorption spectroscopy (AAS). UV-blocking property was determined by UV-vis spectrophotometer. The results of XRD and SEM on the ZnO powders show that we can produce various shape of ZnO. The investigation by SEM and AAS clearly revealed that ZnO in polyvinyl alcohol nanofibers was effectively deposited on the cotton surface. The sphericals-shaped ZnO coated fabrics show excellent UV-blocking properties. The shape of ZnO shows no considerable effect on the tensile strength of the samples.
制备了多种形状的氧化锌，如多花瓣状、棒状和球形，然后将其应用于棉织物以实现紫外线阻隔。通过X射线衍射仪（XRD）和扫描电子显微镜（SEM）对氧化锌颗粒进行了研究。通过静电纺丝将氧化锌与聚乙烯醇的混合溶液施加到棉织物上。通过扫描电子显微镜（SEM）、X射线衍射仪（XRD）、拉伸测试和原子吸收光谱法（AAS）对织物涂层的特性进行了研究。通过紫外可见分光光度计测定紫外线阻隔性能。对氧化锌粉末的X射线衍射仪（XRD）和扫描电子显微镜（SEM）结果表明，我们能够制备出多种形状的氧化锌。扫描电子显微镜（SEM）和原子吸收光谱法（AAS）的研究清楚地表明，聚乙烯醇纳米纤维中的氧化锌有效地沉积在了棉织物表面。球形氧化锌涂层织物表现出优异的紫外线阻隔性能。氧化锌的形状对样品的拉伸强度没有显著影响。
