Abstract
Polyaniline films doped with camphor sulfonic acid have been studied f or electrical resistivity in the temperature range 77-353 K under diff erent thermal conditions. Thermal annealing is found to increase the r esistivity and also its temperature dependence. The temperature above which the resistivity exhibits metallic characteristics is shown to de pend very sensitively on the presence of moisture. We use the inhomoge neously-disordered-metal model to interpret our resistivity results.
