COMPENSATION BEHAVIOR OF ELECTRICALLY CONDUCTIVE POLYTHIOPHENE AND POLYPYRROLE

Thin films of p-type doped polythiophene were found to react rapidly b ut irreversibly with ammonia and water, whereas the loss of conductivi ty was largely reversible by evacuation in p-type doped polypyrrole. T he interaction between compensating agents such as ammonia and water w ith p-type doped polythiophene and polypyrrole has been examined and c hemical reaction schemes have been proposed with the possibility of th eir use in sensing devices.
