The Nanocrystallinity Enhancement of Sol-Gel Derived TiO₂ Nanoparticles by Pre-Hydrothermal Treatment

Abstract:

Nanocomposite thin film containing TiO₂ nanoparticles in polymethyl methacrylate (PMMA) is a new class of potential materials for optoelectronic applications. Among the various processing techniques for these nanocomposites, in situ sol−gel process is well known to be versatile as it enables control of the inorganic-organic interaction at various molecular, nanometer and micrometer scales. However, the resulting TiO₂ phase is largely amorphous, as a consequence of the relatively low processing temperatures. Therefore, the current research is aimed at enhancing the nanocrystallinity of TiO₂ nanoparticles in nanocomposites. For this purpose, pre-hydrothermal treatment was carried on the inorganic sols. The nanocrystallinity degree of the resulting TiO₂ nanoparticles was studied by XRD and FTIR. The studies showed that the nanocrystallinity of TiO₂ nanoparticles synthesized from the inorganic sol can be enhanced significantly by the pre-hydrothermal treatment, as a result of the completion of hydrolysis stage during sol-gel process.
