Abstract
Uniform monoclinite bismuth phosphate (BiPO4) nanorods were fixed on commonly used cotton fabric using two-dip–two-nip technique. Chitosan and acetic acid were applied to act as cross-linking agent in preparing the finishing solution. In this article, BiPO4nanorods modified cotton fabrics for UV-blocking, as well as photocatalytic degradation of RhB has been studied. This coated fabric was characterized by X-ray diffraction, field-emission scanning electron microscopy equipped with energy-dispersive X-ray spectrometer, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and UV–Vis diffuse reflection spectroscopy. Furthermore, UV-blocking and photocatalytic properties were also tested. The coated fabric showed better properties compared to uncoated fabric.
Highlights
Photocatalytic materials and technology have drawn much attention due to their potential use, degradation of dyes and contaminants, absorption of UV light, and optoelectronic[1,2,3,4,5] equipment
UV protection factor (UPF) test and photocatalytic degradation of RhB results showed that the coated fabrics had an excellent UV protection and photocatalytic activity with a good washing fastness
After 10 cycles of washing with soap (0.3 wt%) solution, theses coated fabrics showed a slight decrease in UPF values, which may be due to the removal of BiPO4 nanorods
Summary
Photocatalytic materials and technology have drawn much attention due to their potential use, degradation of dyes and contaminants, absorption of UV light, and optoelectronic[1,2,3,4,5] equipment. There are few studies on the application of BiPO4 for the photocatalytic degradation of organic dyes and UV-blocking fabric finishing agents. UV protection factor (UPF) test and photocatalytic degradation of RhB results showed that the coated fabrics had an excellent UV protection and photocatalytic activity with a good washing fastness.
