HEAT-INDUCED TRANSITION TO THE CONDUCTING STATE IN POLYANILINE DODECYLBENZENESULFONIC ACID COMPLEX

Polyaniline (PANI) doped with dodecylbenzenesulfonic acid (DBSA) is a new conducting polymer complex which combines high electrical conducti vity with processability. The doping reaction of PANI/DBSA has been fo und to be a time-dependent process which can be accelerated by heating . This process has been studied by measuring the conductivity during h eat treatment in complexes with a molar DBSA ratio, relative to PANI, varying from 0.55 to 1.12. The temperature for the onset of conductivi ty depends on the mixture ratio. Conductivities on the order of 1 S/cm were achieved.
