Utilizing Cooperative Proton-Electron Mixed Conduction Induced via Chemical Dedoping of Self-Doped Poly(3,4-ethylenedioxythiophene) Nanofilms for In-Material Physical Reservoirs.

ABSTRACT: In this study, an intrinsic ion-electron (hole) coequally conductive state is introduced, induced by de-doping in self-doped poly(3,4-ethylenedioxythiophene) (S-PEDOT) nanofilms, enhances the performance of in-material physical reservoirs (PRs) through the cooperative utilization of both carriers. A chemical dedoping modulates the electrical characteristics of the S-PEDOT PRs. Impedance spectroscopy under controlled relative humidity (RH) conditions reveals that the predominant conducting carriers of the S-PEDOT nanofilms change systematically depending on the RH. Under low RH, the dominant carriers are holes. At a moderate RH (60-80%), the S-PEDOT nanofilm exhibits a hole-proton mixed conducting state. A further increase in RH leads to predominantly proton carrier conduction. Moreover, th
