Abstract : From a detailed analysis of the behavior of two general type of organic solvents for conducting polyaniline, we conclude that fully protonated polyaniline (ratio H+/PhN=O.5) can be dissolved in a given organic solvent only in cases where the PANI-(acid)O.5 complex is solvated by an appropriate solvating agent. At least 0.5 moles per PANI unit (PhN) of the solvating agent must be present (this amount is dependent on nature of counterion and solvent, for example for very polar counterion in non-polar solvent this value is 1.0). The solvating agent can be the solvent itself if it has strong hydrogen bonding moieties, an excess amount of protonic acid, or some neutral compound with strong hydrogen bonding moieties which is compatible with the solvent. We have shown clearly that the solution properties (solubility, conformation, etc.) of conducting PANI prepare by counterion induced processibility are strongly dependent on the interactions between the polymer chain, the counterions, and the co-solvent. The solid state properties (conductivity, crystallinity, etc.) of a PANI film processed from such a solution are dependent on the choice of counterion, solvent, and co-solvent. The co-solvent can be removed after processing without altering the solid state properties of the resulting polyaniline films or fibers. jg
