T2 - Journal of Applied Polymer Science AB - Electrically conducting polymers are attractive for thermoelectric generators (TEGs) because of their low thermal conductivity and solution processability. In this article, we report on the performance of a radial device made from n- and p-type polymers printed on paper substrates. Our thermoelectric (TE) models predict an optimized geometry for a radial device that operates under natural convective cooling alone, and herein, we report on the fabrication and performance of this new organic TEG. We used poly(nickel-1,1,2,2-ethenetetrathiolate) blended with poly(vinylidene fluoride)/dimethyl sulfoxide as the n-type material and poly(3,4-ethylenedioxythiophene)/poly(styrene sulfonate) with Tellurium nanowires as the p-type materials coated on paper to evaluate the TE performance. The radial TEG produced an open-circuit voltage of 85 mV and a power density of 15 nW/cm2 under a 45-K temperature difference. This proof of concept was the first demonstration of a polymer-based radial TEG that accommodated a hot pipe as the heat source and did not require active cooling because of heat spreading. This is promising for scalable and low cost TE devices for self-powered sensor networks. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017, 134, 44060.
