Effect of TiO2 on the Optical Properties of PANI/TiO2 Nanocomposite Thin Films

Abstract

The effect of TiO₂ nanoparticles (NPs) weight ratio on the properties of PANI/TiO₂ nanocomposite thin films deposited via chemical polymerization onto glass substrates at 0°C were reported. Optical properties studies were carried out in the wavelength region (300-900) nm, optical parameters such as absorbance and transmittance spectra, band gap energy, absorption coefficient, were calculated from the optical data. The results have shown that all optical parameters were affected by increase the TiO₂ NPs weight ratio.
