제목 Robust High Ionic Thermoelectric Harvesting From Conductive Polymer Films
초록 Robust ionic thermoelectric harvesting was investigated from a proton-doped mixed ionic-electronic conductive polymer film coupled with water-harvesting metal organic framework (MOF) film and hydrogel layer (HG). Highly doped poly(3,4-ethylenedioxythiophene)s with poly(styrene sulfonate) (PEDOT:PSS) is prepared by controlling the proton doping to afford a stable and high ionic thermoelectric harvesting. The PEDOT:PSS film doped with 30 wt% of poly(styrene sulfonic acid) (PSSH) showed a Seebeck coefficient of over 16.2 mV K−1. A flexible module-type thermoelectric harvester with 10 legs of this film showed 1.65 V at 5 K and 90% RH. Environmentally sustainable thermoelectric harvesting is achieved under a MOF/HG to provide constant thermovoltage over 72 h at ambient condition.
