Abstract:We compare screen-printed flexible reduced graphene oxide(rGO)-chitosan(CS) supercapacitors (SCs) prepared using poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) pastes and carbon pastes (CPs). SCs with PEDOT:PSS (PEDOT:PSS/rGO-CS SCs) exhibit a higher pseudocapacitance (PC) than do those with CP. Plasma treatment damages the electrodes and lowers the specific capacitance of SCs. In a galvanostatic charge-discharge (GCD) test with a constant current of 0.25 mA, PEDOT:PSS/rGO-CS and CP/rGO-CS… Show more
