Abstract
The subject invention pertains to color changeable, film materials comprising a metal substrate layer; a conducting polymer or conducting polymer composite layer; and an electrolyte layer. The conducting polymer or conducting polymer composite layer of the film material is capable of exhibiting changes in one or more optical properties when the film material is in contact with a metal. The subject invention also pertains to methods of preparing conducting polymer films capable of exhibiting changes in optical properties.
Claims25
A film material comprising:
- a metal substrate or conducting metal oxide coated substrate layer;
- a conducting polymer or conducting polymer composite layer;
- and
- an electrolyte layer in contact with the conducting polymer or conducting polymer composite layer, wherein the electrolyte layer comprises an acidic oxidant,
- wherein the conducting polymer or conducting polymer composite layer exhibits a change in at least one optical property when the film material or electrolyte is in contact with a metal.
A method of preparing a conducting polymer film capable of exhibiting changes in at least one optical property, comprising:
- contacting a substrate with an electrolyte comprising an acidic oxidant;
- and
- contacting the substrate with a conducting polymer or conducting polymer composite solution.
A film material, comprising:
- a conducting metal oxide coated substrate layer, wherein the substrate layer is transparent;
- a conducting polymer or conducting polymer composite layer;
- and
- an electrolyte layer in contact with the conducting polymer or conducting polymer composite layer,
- wherein the conducting polymer or conducting polymer composite layer exhibits a change in the transparency or opaqueness of the composite layer to visible light when the film material or electrolyte is in contact with a metal.
