STRUCTURAL AND ELECTRICAL CHARACTERIZATION OF PROTONIC ACID DOPED POLYPYRROLE
Polypyrrole doped with different protonic acid were chemically synthesized using ammonium persulfate (APS) as an oxidant. These samples were characterized through XRD and FTIR, which confirms the acid doping. I-V characteristics were carried out over the temperature range from 313 K to 483 K, which is found to be linear. The conductivity of PPy [PO 4 3-] is highest among other doped one. Activation energies have been found to be 119.90, 43.94, 58.63 and 65.46 meV for PPy doped with sulfuric, phosphoric, oxalic and acetic acid, respectively
