There have been fascinating breakthroughs in organic thermoelectric (TE) materials/composites during the last several years, some of which are reaching the marketplace. On page 737 (DOI: 10.1002/polb.23482), Qinglin Jiang, Congcong Liu, Jingkun Xu, Baoyang Lu, Haijun Song, Hui Shi, Yuanyuan Yao, and Long Zhang present a simple and economical method for preparing organic TE composites by directly writing poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) solutions on common paper. Improved TE performances, especially the doubled Seebeck coefficient, are achieved. The composite film displays excellent flexibility, a light weight, and soaking stability in water. This new approach can be used to develop high-performance organic TE materials and shows great potential in the large-scale production of organic electronics.
