A simple and easily scalable approach toward the simultaneous synthesis and deposition of conducting plasma‐polymerized 3,4‐ethylenedioxythiophene (ppEDOT) coatings is reported. Our atmospheric‐pressure dielectric barrier discharge (AP‐DBD) approach, operating at room‐temperature and atmospheric‐pressure, does not involve the use of oxidants other than the reactive oxygen species (ROS) formed by the open air Ar/O 2 dielectric barrier discharge. The oxidative polymerization of EDOT is confirmed using UV‐visible (UV‐vis), Raman, and Fourier‐transform infrared (FTIR) spectroscopy. High‐resolution mass spectrometry (HRMS) investigations highlight the discrepancies between the synthesized ppEDOT and conventional PEDOT. Finally, highly transparent (i.e., 98% transmittance) and durable conducting thin films are deposited on polyethylene naphthalate (PEN) foils.
