Conductive polymers are promising materials with considerable interest in a wide range of industries due to their flexibility, excellent optical and electrical properties. Poly(3,4-ethylenedioxythiophene) (PEDOT) is one of the conductive and excellent physical properties compared to other conductive polymers. However, PEDOT has insoluble in water and other solvent, it introduces a primary dopant, polystyrene sulfonic acid (PSSA). It is hydrophilic and has low weather stability in moist atmosphere. As a result, the PEDOT:PSS film exhibit a rapid deterioration in electricla properties under high temperature and high humid conditions. To overcome the problems related to the PSSA, we propose a method of conductive overcoat layer prepared by hybrid composites on a flat conductive film coated on a substrage to improve the stability of conductive polymer.
