摘要: In this work, titanium dioxide (TiO2) nanoparticles were immobilized on the surface of cotton fabrics by in situ reduction polydopamine (PDA) templates. Evidenced results scanning electron microscopy/energy-dispersive X-ray analysis (SEM–EDX), Fourier transform infrared and photoelectron spectroscopy (XPS), PDA films successfully formed as templates for reduction. The morphology, chemical composition crystal structure coated after TiO2 characterized SEM–EDX, XPS diffraction, respectively. These confirmed that anatase well-dispersed fabrics. photocatalysis experiment indicated about 90% methylene blue solution was degraded UV illumination thermogravimetric demonstrated had little effect thermal stability protection showed value ultraviolet factor (UPF) 127.2. UPF maintained at 108.8 five cycles laundering, indicating excellent durability coating terms protection.
