Thermoelectric Properties of One-Dimensional Nanostructures and Composites Based on Polypyrrole

The article emphasizes that conducting polymers could be a worthy alternative to the common inorganic thermoelectrics. It is possible due to specific modification of polymer morphology or composite preparation. The present work gives an outline of the synthesis of one-dimensional (1D) structured polypyrrole nanotubes and polypyrrole composites based on carbon nanotubes. Measurements of specific conductivity and Seebeck coefficient were performed in temperature range from 300 K to 415 K. Based on the results, power factor temperature dependency was calculated and studied. Evaluation of thermoelectric properties changes by specific morphology and composites preparation will help to determine optimal conditions for power factor maximum to reach.
