Abstract
In this paper, the alkali hydrolyzed polyester fabric was treated with functional single-wall and multi-wall carbon nanotubes, nanocarbon black without and with nano-TiO2 and citric acid as a cross-linking agent through exhaustion method and post-curing. Electrical conductivity, methylene blue degradation, UV protection, and thermal stability of the treated fabrics were investigated. The loading of various carbon nanostructures and nano-TiO2 on the polyester fabric confirmed with SEM images and energy-dispersive X-ray spectroscopy. Further, X-ray diffraction, remaining ash percentage via furnace and thermogravimetric analysis, proved the presence of nano-TiO2 on the polyester fabric. The UV protection verified with UV–Vis reflection spectra indicated the highest protection on the nanocarbon black/nano-TiO2/CA-treated fabric. The highest discoloration of methylene blue solution and electrical conductivity obtained on the treated fabric with functional single-wall carbonnano tube/nano-TiO2/citric acid and functional nanocarbon black/nano-TiO2/citric acid. This is related to enhance photocatalytic activities of nano-TiO2 with cooperation of single-wall carbon nanotubes and more surface coating of nanocarbon black on the polyester fabric.
