Abstract
In the present work, Polyaniline doped with Camphor sulfonic acid (CSA) has been synthesized chemically using oxidative polymerization of Aniline taking Ammonium persulfate (APS) as oxidant. The molar ratio of Aniline:CSA:APS was kept as 1:1:1. The conductivity of Polyaniline powder was determined and found to be 4.93 S/cm. The as prepared powder was blended with PMMA at different concentrations using solution casting method taking chloroform as solvent. Their dc conductivity and charge transportation mechanism was analyzed through I-V measurements. A sudden jump of ∼6 orders has been observed in dc conductivity on mixing of 10% by weight of PAni.CSA in PMMA. Furthermore, the charge transportation is also found to be shifting to Poole-Frankel mechanism, which is through Schottky-Richardson mechanism in pure PMMA, on increasing the concentration of PAni.CSA in PMMA.
