| Description | Conducting polymers (such as polyaniline, polypyrrole, polythiophene, or polyindole) are materials widely used from electronics through catalysis to biomedicine. They can be prepared in various forms including thin films, colloids, or conductive gels. Their macroscopic properties, and thus their application potentials, are closely related to their molecular structure and nanostructure – their level of oxidation, the concentration of defects, type of charge carriers, intermolecular interactions, and chain ordering. These properties are reflected in the vibrational spectra of the materials, infrared and Raman spectroscopies are thus widely used methods of studying conducting polymers. In addition, vibrational spectroscopy methods can be coupled with electrochemical experiments which allows for following the molecular structure of the materials in situ. In this doctoral work, the methods of vibrational spectroscopy and spectroelectrochemistry will be applied to perspective conducting polymers (polypyrrole, poly(3,4-ethylendioxythiophene), and polyindole) prepared for applications such as wastewater processing, tissue engineering and electrodes and separators for lithium-ion batteries. |
