Low temperature synthesis of high molecular weight polyaniline using dichromate oxidant.

Adams, PN; Abell, L; Middleton, A; Monkman, AP

Abstract

Aniline was polymerised at temperatures of between 0 and -35 degrees C in acid solution containing lithium chloride and using dichromate oxidant. The optimum temperature to give high molecular weight polyaniline in the emeraldine oxidation state in good yield was found to be -22 +/- 3 degrees C. A solvent cast polyaniline camphorsulfonate film was uniaxially stressed to give a conductivity of 848 +/- 70 Scm(-1) along the stretch direction and 118 +/- 10 Scm(-1) perpendicular to this.
