Thermoelectric Power Factor for Polyaniline/Molybdenum Trioxide Composites

Abstract

The results of thermoelectric power (TEP), power factor and Seebeck coefficient of conducting polyaniline molybdenum trioxide (PANI/MoO ₃ ) composites of different weight percentages (10, 20, 30, 40 and 50wt %) has been reported. The results are supported by the theory of coupled transport equations of heat and electricity in metals. It is observed that even though the Seebeck coefficient decreases with doping, the power factor increases with increase in electrical conductivity. The conductivity results lie between 10 ^{– 5} and 10 ^{– 3} S/cm from 0 wt% to 50wt% of MoO3 in PANI respectively match with that of conventional semiconductors.
