Modific ation of electrode surface w ith sulfonated polyaniline

The dopant incorp orated into inherently conductin g polymers during syn thesis is known to have a substantial effect on the physical and chem ical properties of the resultant material. There has been considerabl e interest in the incor poration of polyelectr oyte as dop ants for conducting polymers. Fully sulfonated polyaniline, poly(۲-methoxyaniline-۵-sulfon ic acid) (PMAS), is a conductive an d electroac tive polyel ectrolyte that has bee n recently used for synthesis of polyaniline with improved p roperties [۱, ۲]. As an acidic polyelectrolyt e PMAS provides counterions, an acidic microenviroment a nd a templa te for electrostatic alignments of aniline monomers for pro ducing the conducting form of p olyaniline. A new approach is described for synthesis of po ly aniline (PAn) on p oly elecrtrolyte modified electro de. The electro de was modified with PMAS.
