Abstract
Due to energy crises, development of renewable energy resources is currently in demand. Having superb physical and chemical properties, optical properties of nanocomposite thin films still need to be enhanced. In the current study, recycled Iron oxide (II) Fe2O3 obtained from rust is reinforced in Polyvinylidene Fluoride (PVDF) by solution casting method and analyzed by UV–visible and FTIR spectroscopy. Various parameters such as band gap, extinction coefficient, refractive index, and dielectric constant are calculated from absorption, and reflectance data. A significant decrease in direct and indirect band gap is noted. An increase in refractive index and improvement in the dielectric constant of nanocomposite thin films is observed. FTIR study confirms the enhancement in the β phase of the Fe2O3/PVDF nanocomposite thin films. Morphology of nanocomposite films is analyzed by using FESEM. Reinforced Fe2O3/PVDF nanocomposite thin films can be used for development of new generation pressure sensors and piezoelectric devices.
