Surface functionalization of nanostructured LaB6-coated Poly Trilobal fabric by magnetron sputtering

[Display omitted] •Nanostructured LaB6 films were deposited on flexible textile substrates by dc magnetron sputtering.•The pronounced influence of the working pressure on the morphologies and optical properties of LaB6 films has been revealed.•The concept of Ultraviolet Protection Factor (UPF) was employed and LaB6-coated PET textiles with ultraviolet protection ability were obtained. Nanostructured LaB6 films were deposited on flexible Poly Trilobal substrates (PET textiles) through direct current magnetron sputtering in order to broaden its applications and realize surface functionalization of polyester fabrics. Characterizations and performances were investigated by employing a scanning electron microscope (SEM), Fourier transformation infrared spectroscopy (FT-IR) and ultraviolet-visible (UV–vis) spectrophotometer. Ultraviolet Protection Factor (UPF) conducted by the integral conversion was employed to measure the ultraviolet protection ability. As expected, the growth of LaB6 film depending on the pressure variation enhanced UV-blocking ability (UPF rating at 30.17) and absorption intensity of the textiles.
