Study of PEDOT conductive polymer films by admittance measurements

▶ Microwave technique to measure the conductivity of PEDOT films. ▶ PEDOT conductivity depends on its mesoscopic scale structure and oxidation level. ▶ Raman spectroscopy and SEM analysis to study structure and morphology of PEDOT. ▶ Microwave measurements allow determination of the macroscopic scale conductivity. ▶ Microwave measurements overcome problems related to the local structural defects and inhomogeneities of PEDOT.
