Effect of Temperature on the Polymerization and Optical Conductivity of Thin Flexible Polypyrrole/Starch Composites. (May 2020) - Mudila, Harish
Abstract: Conductive PPY/Starch (PS) composites were prepared at varying temperature by insitu polymerization method. These polymerized materials were subjected to various studies viz. UV-Vis, FTIR, and XRD to study their effective interaction with each other. The impact of polymerization temperature on the optical conductivity of all the fabricated materials and individual components were studied, these studies shows the increased amount of conductive PPY in the composites leads towards higher optical conductivity of fabricated composites. The PPY/Starch composite synthesized at 0±1°C was observed to have the optical band gap of 4.9 eV and optical conductivity of ∼2.8×10 8 S −1 at 290 nm, which is decent for a material to be used as an optical conductive and hence the proposed material find its application in diverse field of energy storage.
