The directly photopatternable PEDOT:PSS film PEDOT as such has a better conductivity and stretchability compared to its other counterparts. The directly photopatternable PEDOT:PSS film can further be supplemented with poly(ethylene glycol) diacrylate (PEGDA) which can help with the removal of PSS. Advantageously, the PEGDA supplemented PEDOT:PSS film can exhibit a larger charge storage capacity.
