POLYMER TECHNOLOGY
• PEDT is a conductive organic polymer
Polymerization reaction with monomer and oxidant
at lower temperature; ‘soft thin film’ – NON-
STRESS 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.
• MnO2 is manganese dioxide
Brittle semiconductor material obtained by
thermal decomposition at ~260ºC of manganese
nitrate – STRESSED INTERFACE
