Synthesis and characterization of new copolymer of pyrrole and 3,4-ethylenedioxythiophene synthesized by electrochemical route

• P(Py-co-EDOT) copolymer prepared by simple electropolymerization technique.
• Structure characterized by FTIR, XRD, SEM/EDX, and elemental analysis.
• Physicochemical properties of the new copolymer studied by means of TG–DTA, DSC, and CV.
• Quantum chemical calculations have been made to interpret the polymerization on molecular level.
• Electrical properties and iodine doping process have been studied.

A copolymer of pyrrole (Py) and 3,4-ethylenedioxythiophene (EDOT) was electrochemically synthesized on ITO electrode by using potentiodynamic method in acetonitrile with tetrabutylammonium tetrafluoroborate (Bu4NBF4). The product poly(pyrrole/3,4-ethylenedioxythiophene) P(Py-co-EDOT) was characterized via CV, FTIR and SEM. Copolymer film has distinct properties, i.e., these were homogeneous and exhibited good electrochemical properties.
