Description
Summary:An electrode comprising two metal strips separated by a very small gap is used for in situ electrical conductivity measurements of electrochemically synthesized intrinsically conducting polymers. With a newly developed electronic circuit based on standard analogue devices, d.c. conductivity measurements of polymer films deposited on this electrode are greatly simplified. The application of the electrode and the measurement circuit are demonstrated by representative results obtained with polyaniline at various doping states. For comparison simultaneous a.c. conductivity measurements using the same electrode set-up are shown and an explanation of the results is presented.
