Abstract

For effective use of conducting polymers, a hybrid film composed of poly (3,4-ethylenedioxythiophene) : poly (styrenesulfonate) (PEDOT:PSS) and poly (3,4-ethylenedioxythiophene) (PEDOT) has been fabricated by a in situ polymerization method. Each component in the hybrid film provides unique and crucial function to achieve optimized electrochemical properties. In the presence of PEDOT:PSS, the PS/PEDOT hybrid film is found to possess the better energy storage ability. Volumetric capacity of composite film (97.51 F/cm3) is much higher than that of pure PEDOT:PSS (37.75 F/cm3) and PEDOT (50.52 F/cm3 ) films. The hybrid film also exhibits excellent charge/discharge rate and good cycling stability, retaining 92.4% of its initial charge after 1000 cycles. The electrochemical performance improvement is primarily due to the synergistic effect between PEDOT:PSS and PEDOT. It is anticipated that this flexible procedure could be a promising large scale fabrication method for supercapacitor electrodes.
