“…The origin of MIECs comes from inorganic systems that are widely studied and previously applied in membranes and fuel cells, showing an outstanding ionic conductivity and thermal stability. Nevertheless, the properties of π-conjugated conducting polymers, which are intrinsic MIECs, such as semimetallic electronic conductivity, reversible electrochemical activity, and ease of manufacturing, make them highly promising materials that could act as binders as well …”

Mixed conductors having both high ionic and electronic conductivities are needed in membrane electrode assemblies (MEAs) present in electrochemical devices from fuel cells to supercapacitors and all battery chemistries. Typically, carbon black, binders, and redox-active materials are combined to make an electrode assembly, into which a liquid electrolyte can impregnate. Solid-state devices require the ionic conduction built into the MEA. In this case, a material which can provide both electronic and ionic conduction as well as a redox functionality is described based on PEDOT−Cl as both the electronic conductor and the redox active component, while an organic ionic plastic crystal [C 2 mpyr][FSI] is present as both the binder and ionic conductor. Surprisingly, both the electronic and ionic conductivities of the composite are enhanced relative to the pure components by a factor of ×9 for electronic and ×180 for ionic conductivities. The mixed conducting composites are demonstrated to retain their redox activity in aqueous electrolytes, and in the optimum case, 103 F g −1 and 296 mF cm −2 capacitance values are obtained for low-and high-mass loading electrodes. These materials demonstrate an innovative approach to prepare electrode assemblies where all three functionalities are incorporated into the materials, that is, electronic, ionic, and redox activity for future energy devices.

“…One of the most promising materials so far for OECTs is the low-bandgap conducting polymer poly (3,4ethylenedioxythiophene) (PEDOT), owing to its high conductivity, environmental stability, and water dispersibility in the form of poly (3,4-ethylenedioxythiophene)/poly (styrene sulfonic acid) (PEDOT:PSS) [20][21][22]. Compared with the traditional electrochemical transistors, fiber-based OECTs have attracted great attentions due to the advantages of adjustable fabrication, good air stability, low driving voltages, compatibility with flexible substrate, and low cost over large areas [23][24][25][26][27][28]. By embedding the electronic functional components into fabrics, fiber-based OECTs facilitate the rapid development of functional circuits on textile materials and provide various compelling applications including dynamic health monitoring, wearable smart computers, and light-emitting diodes (LEDs) [29].…”

Contact electrification-activated triboelectric potential offers an efficient route to tuning the transport properties in semiconductor devices through electrolyte dielectrics, i.e., triboiontronics. Organic electrochemical transistors (OECTs) make more effective use of ion injection in the electrolyte dielectrics by changing the doping state of the semiconductor channel. However, the mainstream flexible/wearable electronics and OECT-based devices are usually modulated by electrical signals and constructed in conventional geometry, which lack direct and efficient interaction between the external environment and functional electronic devices. Here, we demonstrate a fiber-shaped triboiontronic electrochemical transistor with good electrical performances, including a current on/off ratio as high as ≈1286 with off-current at ~nA level, the average threshold displacements (Dth) of 0.3 mm, the subthreshold swing corresponding to displacement (SSD) at 1.6 mm/dec, and excellent flexibility and durability. The proposed triboiontronic electrochemical transistor has great potential to be used in flexible, functional, and smart self-powered electronic textile.
