PHOTOCATALYTIC PROPERTIES OF TEXTILES SPUTTER COATED WITH TiO2
Nanoscale titanium dioxide (TiO2) films were deposited on the surface of cotton fabric and polyester (PET) fabric by RF magnetron sputter coating. The surface morphology of the coated fabrics was examined by Atomic Force Microscope (AFM). A specifically designed reactor was used to assess the effects of different types of coated fabrics on formaldehyde removal efficiency, and their photocatalytic activity to remove formaldehyde by different types of TiO2 coated fabrics was also compared. The AFM observations revealed the nanostructure of TiO2 clusters formed on the fiber surface of the coated fabrics. The AFM images also indicated that the functional nanostructures formed on the cotton fibers were quite dissimilar to those on the PET fibers under the same coating conditions. This dissimilarity is believed to be caused by the differences in the surface morphology and hydrophilicity between cotton and PET fibers. The cotton fabric coated with nanoscale titanium dioxide showed higher the formaldehyde removal efficiency than the polyester fabric coated nanoscale titanium dioxide under same conditions.
