- 4. Polymer Capacitors Cathode Differences • PEDT is a conductive organic polymer Polymerization reaction with monomer and oxidant at lower temperature; ‘soft thin film’ – NON-STRESS INTERFACE • MnO2 is Manganese Dioxide Brittle semiconductor material obtained by thermal decomposition at ~260ºC of manganese nitrate – STRESSED INTERFACE PEDT MnO2 PEDOT (poly-ethylenedioxythiophene) is technically classified as a semiconductor; however, it is highly conductive relative to MnO2. The conductivity for PEDOT is in the range of 100 to 1,000 S/cm, while MnO2 is in the range of 1 to 10 S/cm.
