There are provided a method for forming a polybenzimidazole coating on a surface of a substrate, and a method for forming a polybenzimidazole film. The method for forming a polybenzimidazole coating comprises the steps of: coating a solution containing a polybenzimidazole prepolymer onto a surface of a substrate; and heating the coated substrate to cyclize the prepolymer and thus to form a cured coating on the surface of the substrate. The method for forming a polybenzimidazole film comprises separating the cured coating, formed by the above method, from the substrate.
