Intensification of Conductivity and Solubility of Polypyrrole Using Acrylic Acid and Polyacrylic Acid Dopants

摘要

Doped polypyrrole (PPy) was synthesized using FeCl3 as an oxidant, acrylic acid and poly(acrylic acid) as dopants. The effects of dopants and doping level on the solubility and conductivity parameters were optimized. The doped PPy was characterized using FT-IR, UV-Vis and EPR measurements. The thermal stability of doped PPy was studied by TGA/DSC analysis. The morphology of the doped PPy was studied using Scanning Electron Microscope. The Electrochemical study of the doped PPy was carried out by Electrochemical Impedance Spectroscopy (EIS). This study reveals that the polyacrylic acid doped PPy shows higher conductivity than its monomer acrylic acid and the water soluble nature was also augmented at higher doping level of polyacrylic acid on the PPy.
