Crown ether enabled enhancement of ionic–electronic properties of PEDOT:PSS

Abstract

Poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) based organic electrochemical transistors (OECTs) have proven to be one of the most versatile platforms for various applications including bioelectronics, neuromorphic computing and soft robotics. The use...

A high-performance organic electrochemical transistor based on foam-structured channels prepared using a template washing-off method

“…As reported, the performance (e.g., transconductance) of OECTs is closely related to the geometry and electrical properties of the channel layer. 24 The relationship can be expressed with the following formula:…”

Proton-penetrable Nafion-induced phase separation in organic semiconductors for high-performance organic electrochemical transistors

“…2b), suggesting phase separation. 38,45 Then, the surface morphology of the Nafion-including PEDOT:PSS film was investigated by atomic force microscopy (AFM). The Nafion-including PEDOT:PSS film showed a high roughness of 3.3 nm and two different phases could be observed in the phase image (Fig.…”

“…44 To date, the materials used for physical mixing with the organic semiconductor have been limited mainly to low molecular amount ones. 45,46 Therefore, the mechanical and chemical stabilities of the obtained OECTs are not high enough. Therefore, it is still necessary and urgent to develop a simple and efficient method to improve the semiconductor layer in OECTs.…”
