Abstract: Polypyrrole samples doped with sulfuric acid have been synthesized by using chemical oxidative polymerisation technique in different ways. The monomer mixed with acid (sample S₁) and oxidant mixed with acid (sample S₂) is characterized by XRD and FTIR spectroscopy. Electrical conduction in these doped samples are studied through the I-V measurements at room temperature as well as function of temperature from 313 to 473 K. The I-V lharacteristics for both the samples have been found to be linear but conductivity of sample S₂ is found to be higher. Temperature dependence of conductivity suggests a transition from semiconducting nature to metallic nature with increase in temperature. Activation energies for both the samples have been found to be in milli electron volt range, 96.76 meV and 116.72 meV for samples S₁ and S₂, respectively.
