Synthesis of alcotex/3-aminopropanoic acid polymer thin film and its structural and opto-electrical properties

We report that alcotex/3-aminopropanoic acid (PVA-beta-alanine) polymer thin film was synthesized by taking different concentrations of PVA-beta-alanine by the solution casting process, and their structural, opto-electrical and ionic conductivity were examined for the first time. In the X-ray diffraction (XRD) study, the crystallite structure of the semi-crystalline film can be clearly seen with an increase in beta-alanine and a decrease in the PVA concentrations. The presence of functional groups and optical response was analyzed for the prepared material using the Fourier Transform Infrared (FT-IR) and optical absorption tests. The wider optical band gap values are calculated to be 4.89 to 5.07 eV using the Tauc plots for polymer thin film materials at various PVA-beta-alanine concentrations. The effects of various PVA/beta-alanine wt% concentrations on the ionic conductivity, electrochemical impedance spectroscopy (EIS) parameters, power-law exponent (n) and hopping frequency of the prepared polymer films have been elucidated.
