چکیده

Abstract Large area manufacturing of printed electronic components on ~A4‐sized substrates is demonstrated by the combination screen printing and vapor phase polymerization (VPP) into poly(3,4‐ethylenedioxythiophene) (PEDOT). The oxidant layer required for process printed, resulting conductive polymer patterns are manufactured at high resolution (100 µm). Successful processing several common species demonstrated, thickness can be adjusted altering time. By comparing films this work to a commercial PEDOT:PSS (PEDOT doped with poly(styrene sulfonate)) ink shows improved surface roughness (26 vs 69 nm), higher conductivity (500 100 S cm –1 ) better 200 Organic electrochemical transistors, in which transistor channel polymerized PEDOT through VPP, also further emphasize applicability approach. devices not only functional, they show remarkable switching behavior respect ON current levels (–70 mA V), ON/OFF ratios (>10 5 ), times (tens ms) transconductance values (>100 mS) standalone devices, addition amplification factor (>30) upon integration inverter circuit.
