We demonstrate a facile method to fabricate macroporous poly (3,4-ethylenedioxythiophene)/poly (4-styrene sulfonate) (PEDOT/PSS) films with empty channels by using electrospun nanofiber as a sacrificial template. The channels within the PEDOT/PSS films were prepared by depositing PEDOT/PSS aqueous dispersion onto poly (vinyl pyrrolidone)/poly(methyl methacrylate) (PVP/PMMA) nanofiber template, and then the nanofibers were removed by solvent extraction. The average diameter of the channels is 313±45 nm, which is almost the same as the parent PVP/PMMA nanofibers. The macroporous PEDOT/PSS film with the empty channels showed an enhancement of electromechanical properties compared to the nonporous PEDOT/PSS film.
