Synthesis and Characterization of Polymeric (PMMA-PVA) Hybrid Thin Films Doped with TiO2 Nanoparticles Using Dip-Coating Technique

We report the synthesis of hybrid thin films based on Poly(MethylMethAcrylate) (PMMA) and Poly(VinylAlcohol) (PVA), doped with different concentrations titanium dioxide nanoparticles (TiO2 NPs). As-prepared (PMMA-PVA) by TiO2 NPs (wt.% = 2%, 4%, 8%, 16%) are deposited glass substrate. Transmittance (T%), reflectance (R%), absorption coefficient (?), optical constants (n k), dielectric functions (?1 ?2) deduced using experimental transmittance spectra. Furthermore, a combination classical models such as Tauc, Urbach, Spitzer-Fan, Drude applied to calculate optoelectronic parameters energy gaps prepared nanocomposite films. The bandgap PMMA-PVA film is found be 4.101 eV. Incorporation into polymeric leads decrease in thus engineering possible. Fourier-transform infrared spectroscopy (FTIR) spectra measured interpreted identify vibrational modes. To elucidate chemical stability, thermogravimetric (TGA) curves measured. that (PMMA-PVA)/TiO2 thermally stable below 110 °C enable them attractive for wide range applications.
