Abstract
We have studied the electrical properties for conductive polyaniline (PANI) and polypyrrole (PPy). Also, bilayer structures consisted of electrochemically deposited PPy and PANI films onto PPy and PANI substrates prepared by chemical oxidative polymerization were investigated. In order to obtain structures with a high stability of electrical properties, the dopants compatibility with the polymers was studied. Special attention is given to I-V characteristics of the structures. On the basis of the experimental results, the electrical properties of bilayer structures based on PPy and PANI combined by different ways are described. In addition, the adhesive properties of different adherent layers, one to another, are discussed.
