Abstract
A novel strategy via paper as an effective substrate has been introduced as a thermoelectric material in this work. Free-standing poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS)/paper composite films are conveniently prepared by a one-step method of directly writing PEDOT:PSS solution on paper, making the process simple, rapid, and facile. The free-standing composite films display excellent flexibility, light weight, soaking stability in water, and great potential in large-scale production. Improved thermoelectric properties are obtained in PEDOT:PSS/paper composite films, owing to the simultaneously enhanced Seebeck coefficient (30.6 uV K−1) and electrical conductivity, and a low thermal conductivity (0.16 W m−1 K−1) compared with pristine PEDOT:PSS films. The results indicate that paper as an effective substrate is suitable for the preparation of high-performance and flexible thermoelectric materials. © 2014 Wiley Periodicals, Inc. J. Polym.

Additional information
There have been fascinating breakthroughs in organic thermoelectric (TE) materials/composites during the last several years, some of which are already reaching the marketplace. In Xu and Lu’s lab, a simple and economical method was presented for preparing organic TE composites by directly writing poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) solutions on commercial paper. Improved TE performances, especially doubled Seebeck coefficient, were achieved. The composite film also displayed excellent flexibility, a light weight, and soaking stability in water. This new approach can be employed to develop high-performance organic TE materials and shows great potential in the large-scale production of organic electronics.
