Abstract
A method of manufacturing a conducting polymer film including dissolving a lithium salt in an organic solvent; after the lithium salt is completely dissolved in the organic solvent, dissolving a conducting polymer in the organic solvent by adding the conducting polymer little by little in many separate doses into the organic solvent until obtaining a deep blue colored solution; and leaving the deep blue colored solution as it stands over seven days and coating it on a flat surface; and evaporating the solvent from the coated solution. It is possible to work the conducting polymer film in a very thin membrane and to control the thickness as required, since the polymer film can be formed directly from a solution. Furthermore, it is also possible to control the conductivity of the polymer film by varying the type of salts as used and the concentration thereof, and thus its applicability is very diverse as the purpose of using them, for example in electronic/electric components.
