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
