When washed, dried and doped with LiCIO .. , the bilayer showed electrochemical activity corresponding to doping and undoping reactions in the solid state. The bilayer was characterized by FT-IR (reflection), UV spectroscopy and microscopic examination while the electrochemical activity in the solid state was examined by cyclic voltammetry. Cyclic voltammetry of the composite conductive polymer and polymer electrolyte in the solid state againstPt produced oxidation peaks at 0.26 and 0.78 V. Against Li, a broad oxidation peak appeared between 0.5 and 4.5 V; doping efficiency in the Li cell reached 95% between 2-4 V at a scan rate of 100 m VIs. The color of the conducting polymer as anode changed from transparent yellow to green and then to blue during the doping process. Cole-cole plots of the composite obtained by AC impedance measurements showed an arc at high frequency region (> 2.82 MHz) due to polymer electrolyte impedance. Another arc due to impedance of the doping reaction, at lower frequency (> 20 Hz) followed as doping of the conductive polymer proceeded; the arc is then joined by a Warburg line, which characterizes diffusion controlled kinetics at the low frequency region « 20 Hz).0 650 4 aChemistry0 650 4 aPolyaniline0 650 4 aPolythyleneoxide PEO network0 650 4 aElectron conducting polymer0 650 4 aIonic conducting polymer bilayer 991 # wANALYTICS           Physical Location           Digital Copy Not Available          Add to Book Cart  |   Download MARC
