SOLUTION PROPERTIES OF CONDUCTING POLYANILINE INDUCED BY SOLVENT QUALITY

Polyaniline doped with organic dopants such as camphorsulfonic acid wa s prepared in different organic solvents. The doped polyanilne in m-cr esol solution behaves as a weak polyelectrolyte and in chloroform as a neutral polymer. The number of effectively doped sites of polyaniline is controlled by the solvent quality and instead of the compact coil- to-expanded coil model an alternative model has been proposed based on the solvent quality.
