Abstract: A method of manufacturing a film or membrane includes: (a) dissolving at least one polymer comprising a poly(aryl ketone) in at least one solvent to form a dope; (b) depositing the dope on a substrate to form a coated substrate at appropriate conditions; and (c) drying the coated substrate to form the film or membrane. The dope may also include additional polymers or fillers, such as carbon nanotubes.
