Conducting polymer-based electrodes have drawn much attention in the fields of bioelectronics and ion storage devices due to high gravimetric capacitances enhanced by their ion-permeability and electrochemical activities. Herein, we demonstrated poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) [PEDOT:PSS] microfiber mesh-based pseudocapacitors with good electrical conductivity and ion permeability. The microfiber meshes were fabricated by simple wet-spinning, cutting, and self-healing, and the resultant mesh network with overall thickness over hundreds of micrometer showed high gravimetric capacitance over 50 F/g, decent electrical conductivity of 1 kS/cm, and stable electrochemical properties during repeated charging/discharging cycles without apparent performance degradation. |
