Abstract:
A method of manufacturing a light-transmissive, low-ohmic coating on a substrate, characterized in that the coating is manufactured byproviding the substrate with a porous layer comprising high index material having an index of refraction which is higher than the substrate, subsequently applying a coating solution of a monomer of which the polymer is conductive and an Fe(III) salt on the substrate, whereafter a treatment at an increased temperature is carried out, thereby forming a layer comprising a conductive polymer and an Fe(II) salt, after which the double layer is rinsed with an ethanolic solution which is capable of extracting Fe salts, thereby forming a first layer having an index of refraction which is higher than the index of refraction of the substrate and a second layer forming an electroconductive layer having an index of refraction which is lower than the index of refraction of the substrate.
