From the author: The electrical transport properties of hydroiodic acid doped polyaniline in the temperature range 77 [less than or equal to] T [less than or equal to] 300 K were studied. The magnetic field strength was varied to a maximum of 1T in the frequency range of 20 Hz-1 MHz. The ac conductivity followed the universal dielectric response [sigma] (f) [proportional] [f.sup.s]. The trend in the variation of 's', the temperature dependence of the frequency exponent, indicated that correlated barrier hopping is the dominating charge transport mechanism. The ac conductivity also shows a positive variation with magnetic field, which can be interpreted by Maxwell-Wagner capacitor model. POLYM. ENG. SCI., 49:910-915, 2009.
