Abstract The thermoelectric (TE) properties of organic/inorganic composite materials have been extensively studied for nearly one decade but there still has no significant breakthrough. Herein, we developed a facile method to prepare poly(3,4-ethylenedioxythiophene) (PEDOT)/Ag2Se/CuAgSe ternary composite films with ultrahigh performance and superior flexibility. First, PEDOT:poly(styrenesulfonate) (PSS)–coated Se (PC-Se) nanowires (NWs) were chemically in situ synthesized, then the PC-Se NWs were used as templates to prepare PEDOT:PSS coated Ag2Se/CuAgSe NWs, and finally highly flexible PEDOT/Ag2Se/CuAgSe ternary composite films on porous nylon membrane were fabricated by vacuum assisted filtration and then hot pressing. An optimized composite film with hierarchical microstructure defects shows a record power factor (PF) of ~1603 μW m−1 K−2 (corresponding 0.6

用于可穿戴热电发电机的超高性能 PEDOT/Ag2Se/CuAgSe 复合薄膜

摘要 有机/无机复合材料的热电（TE）性能已被广泛研究近十年，但仍未取得重大突破。在此，我们开发了一种简便的方法来制备具有超高性能和优异柔韧性的聚（3,4-乙撑二氧噻吩）（PEDOT）/Ag2Se/CuAgSe 三元复合薄膜。首先，PEDOT:聚（苯乙烯磺酸盐）（PSS）包覆的Se（PC-Se）纳米线（NWs）被化学原位合成，然后PC-Se NWs作为模板制备PEDOT:PSS包覆的Ag2Se/CuAgSe NWs，最后通过真空辅助过滤然后热压在多孔尼龙膜上制备高柔性PEDOT/Ag2Se/CuAgSe三元复合膜。
