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 conductivity with processability. The doping reaction of PANI/DBSA has been found to be a time-dependent process which can be accelerated by heating. This process has b...

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