The evaluation of electrical conductivity for pi-conjugated polymers is one of the most important areas for several electronic applications. To measure the electrical conductivity (or) of a pi-conjugated polymer thin-film, we attempted to use surface plasmon resonance (SPR). DC conductivity of the polymer thin-film was also measured by the traditional van der Pauw method and compared with the results derived from SPR method. These two conductivity values of the polymer thin-film obtained by different methods were very similar.
