One or more embodiments relate to an electrically conductive polymer with a crosslinkable additive. The electrically conductive polymer is a directly photopatternable Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) PEDOT:PSS film with cross-linked network made of a plurality of monomers. 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.
