The addition of ethylene glycol (EG) in the PEDOT:PSS solution can dramatically enhance the conductivity of the polymer film. Furthermore, the solvent treatment induces the reorganization of the polymer chains, leading to better distribution of PEDOT:PSS on the AgNW network. With the EG-enhanced AgNWs/PEDOT:PSS electrode, an 87% transmittance of the nanocomposite electrode can be achieved at a wavelength of 550 nm and a pseudo capacitance of 113 ± 18 F/g (areal capacitance = 2.83 ± 0.46 mF cm-2) can be achieved at a scan rate of 10 mV/s. When it was stretched with a tensile strain of 40%, the capacitance of the transparent supercapacitor even increased, owing to closer electrode contact. This work provides a facile way to produce highly transparent and stretchable electrodes using EG-enhanced nanocomposite for a stretchable portable power source of transparent electronics. ?Aliphatic compounds; Capacitance; Conducting polymers; Ethylene; Ethylene glycol; Mobile power plants; Nanocomposites; Polymer films; Polyols; Semiconducting films; Silver nanowires; Supercapacitor; Tensile strain; Nanocomposite electrodes; Poly(styrene sulfonate); Poly-3 ,4-ethylenedioxythiophene; Polymer nanocomposite; Portable power sources; Pseudo capacitances; Stretchable electrodes; Transparent electronics; Transparent electrodesjournal article10.1021/acsaem.0c027812-s2.0-85102469117
