Abstract: | 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. |
