AN INVESTIGATION OF ELECTROCHEMICALLY AND CHEMICALLY POLYMERIZED INDOLE

Doped polyindole can be obtained either after anodic oxidation of indo le, C8NH7, in various electrolytic solutions or after indole chemical oxidation in acetonitrile - oxidizing agent (FeCl3, CuCl2, KIO3) solut ions. This conducting polymer exhibits a good air stability with room temperature electrical conductivities, in the range 10(-3) to 10(-1) S .cm-1, depending on the nature of the counterion and on the polymeriza tion process. The influence of the experimental synthesis conditions o n the morphology of the chemically obtained polyindole is examined.
