Investigation of the electrochemical stability of conducting polymer films and thin metal layers

Description of the research topic

In recent years there has been great progress in research on electronic and electrochemical devices based on organic materials. In such devices polymers are often deposited on polycrystalline thin metal layers, however, microelectronic devices which utilize polymers coated with patterned thin metal films have also been developed. Many of the above devices work in an electrochemical environment and can be considered to be “modified electrodes”. The distinguishing feature of a modified electrode is that a generally quite thin film (from monomolecular to a few micrometers thick multilayer) of a selected chemical is bonded to or coated on the electrode surface to endow the electrode with the chemical, electrochemical, optical, transport, and other desirable properties of the film in a rational, chemically designed manner, but more complex structures also exist, they may contain more than one modifying substance, or more than one layer. It is beyond question that the monitoring of the degradation of the different (functional) layers is of great importance for the efficient use of these devices. The main objectives of the research project are: a better understanding of the degradation processes in modified electrodes and electrode materials and the development of new electrochemical techniques for the monitoring of the degradation of conducting polymer films and thin metal layers in modified electrodes, gaining new information on electrochemical processes of theoretical and/or practical importance, and a better understanding of complex electrochemical reaction mechanisms.
