Typical conducting polymers (CPs) have low thermal conductivity and relatively high electrical conductivity that make it of interest for thermoelectric community. Polyaniline (PANI) has a greater potential for thermoelectric application as it combines higher environmental and thermal stability with the CPs thermoelectric behavior. In this work, PANI was prepared via chemical oxidative polymerization technique using ferric chloride initiator. A complete study of PANI synthesis parameters; medium acidity, initiator concentration, time and temperature effect on its thermoelectric behavior is conducted. Composites of PANI with different percentages of carbon nanotubes (CNTs) and graphene were prepared via different methods of solution-assistant dispersing and physical blending method. The prepared composites showed higher outstanding thermoelectric properties than that of pristine PANI samples. The enhanced thermoelectric behavior could be attributed to the л-л conjugation between PANI and the filler materials.
