Conteúdo: |
The electrical properties of polyanilines are highly dependent on the polymer oxidation state. In order to obtain a simple method to determine the polymer oxidation state a systematic study was carried out to investigate the interconversion between the oxidation state by ultraviolet-visible spectroscopy. The emeraldine base oxidation state is obtained where the exciton peak is a maximum for each derivative. The variation of oxidation state as a function of wavelength and absorption in the UV-Vis analysis is discussed. |
