  • We are most grateful to referees of our paper who drew our attention to the fact that a combination of SP with SEM, gas adsorption measurements etc. could shed new light on doping-induced morphological changes resulting from the non-rigidity of the structure of intrinsically conductive polymers, their swelling, different types of interactions between macromolecules, and between macromolecules and the solvents. All these factors can in principle manifest themselves in different morphological architectures. The authors wish to thank E. Genies, E. Vieil, and Y. Nicolau for stimulating discussions.

Abstract

Standard porosimetry is a new technique for measuring the pore radius distribution in microporous materials. Comparison of the porous structure parameters obtained by this technique and by gas adsorption measurements and SEM, both established methods, on polyaniline emeraldine salts and bases demonstrates that standard porosimetry can be used for the characterization of the porous structure of powders of conductive polymers and that this novel method has several advantages.
