Abstract
Titania was deposited on glass fibers with a partial epoxy layer coating from a solution containing TiO2 nanoparticles at T = 90 °C, and the adsorption process was examined by X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), Fourier transform infrared (FT-IR) spectroscopy, and photocatalytic activity measurements. XPS data demonstrated that about 25% of the surface was covered with TiO2 nanoparticles, with 10% on the epoxy layer and 15% on the glass body. It was found that TiO2 nanoparticles can be readily adsorbed on epoxy groups, whereas they have a low tendency to adsorb on carbon polymer chains. This difference can be attributed to the hydrogen bonding between the hydroxyl groups on the surface of TiO2 nanoparticles and the hydroxyl groups resulting from the acid-catalyzed epoxy ring opening. This hypothesis was verified by removing the epoxy groups on top through preheating of the fibers at 500 °C and studying the surface coverage after...
