Poly(3,4-ethylenedioxythiophene) doped with poly(4-styrene sulfonate) (PEDOT: PSS) films have strong potential for application in flexible transparent conductive electrodes. In this study, the electrical conductivity of PEDOT: PSS is shown to be enhanced by a bisphenol additive, bis (4-hydroxyphenyl) sulfone (BPS). The effects of BPS on the chemical structure of PEDOT: PSS were investigated using X-ray diffraction, Fourier transform infrared (FTIR) spectroscopy, and transmission electron microscopy. The PEDOT: PSS conformation is found to undergo a transformation into a highly conductive structure following the addition of BPS.
