Charge Transport Through Polypyrrole and Single-Walled Carbon Nanotube Composite: A Thermoelectric Material

A polypyrrole-single-walled carbon nanotube (PPY-SWCNT) has been prepared with 5 wt.% of single-walled carbon nanotubes (SWCNT) employing chemical oxidative in situ polymerization to compare the thermoelectric properties of polypyrrole (PPY) and the composite. The composite formation has been discussed based on the carrier transport mechanism through the composite. Transport parameters have been calculated and correlated with the structure formation. Dependence of carrier concentration and mobility of charge carrier on temperature has been obtained based on the charge carrier transport in PPY and PPY-SWCNT composite.
