Thermoelectric Properties of Alternatively Layered Films of Polyaniline and (±)-10-Camphorsulfonic Acid-Doped Polyaniline

Thermoelectric performance of polyaniline can be improved by formation of multilayered film structure. The alternatively layered films are composed of electrically insulating emeraldine base layers and electrically conducting (±)-10-camphorsulfonic acid (CSA)-doped emeraldine salt layers. The multilayered film exhibited 3.5 times higher thermoelectric power factor at ca. 300 K than a bulk film of polyaniline doped by CSA.
