本文报道了纳米氧化锌的合成、表征及其在棉、毛织物上的应用。在不同的温度（90或150 ℃）和反应介质（水或1，2-乙烷）条件下制备纳米颗粒。高温是获得小的单分散颗粒所必需的。采用傅里叶变换红外光谱（FTIR）、透射电子显微镜（TEM）和X射线粉末衍射（XRD）对纳米颗粒的组成、形状、尺寸和结晶度进行了表征。还测定了干燥粉末的比表面积。然后将ZnO纳米颗粒施加到棉和羊毛样品上，以赋予经处理的纺织品防晒活性。通过紫外-可见分光光度法和紫外线防护因子（UPF）的计算来评估治疗的有效性。在用ZnO纳米颗粒处理之前和之后对织物进行物理测试（拉伸强度和伸长率）。
We report the synthesis and characterization of nanosized zinc oxide particles and their application on cotton and wool fabrics for UV shielding. The nanoparticles were produced in different conditions of temperature (90 or 150 C) and reacting medium (water or 1,2-ethanediol). A high temperature was necessary to obtain small monodispersed particles. Fourier transformed infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and X-ray powder diffractometry (XRD) were used to characterize the nanoparticles composition, their shape, size and crystallinity. The specific surface area of the dry powders was also determined. ZnO nanoparticles were then applied to cotton and wool samples to impart sunscreen activity to the treated textiles. The effectiveness of the treatment was assessed through UV-Vis spectrophotometry and the calculation of the ultraviolet protection factor (UPF). Physical tests (tensile strength and elongation) were performed on the fabrics before and after the treatment with ZnO nanoparticles.
