Preparation and Photocatalytic Properties of PEG-Silicone Polyesters/Titanium Dioxide Nanotube Composites

This study uses a series of hydrophilic PEG-silicone polyester and titanium dioxide nanotubes to prepare high-performance titanium dioxide nanotube (TNT) composites. The decomposition of these titanium dioxide nanotube composites for the methylene blue is investigated by using UV-Vis spectroscopy. These changes in structure have been observed by FTIR and Raman analysis at 365 nm UV irradiation. The surface microstructures of composites were characterized with scanning electron microscopy (SEM). It was found that titanium dioxide nanotube composites possessed excellent solubility and dispersion effects. This makes fixation of photocatalysts possible and retards oxidation of organic materials in the PEG-silicone polyesters.
