Fully protonated polyaniline: Hopping transport on a mesoscopic scale

Physical review. B, Condensed matter (1994)

Rolf Pelster G. Nimtz Bernhard Weßling

In order to clarify the transport mechanism in fully protanated highly conductive polyaniline the origin and size of the electronic localization centers and barriers have to be determined. Dispersions of polyaniline in an insulating polymer have been studied by temperature-dependent broadband dielectric spectroscopy (5 Hz to 2 GHz, 100--320 K). The electronic transport in the blends and in pure polyaniline is shown to be governed by three-dimensional (3D) hopping between mesoscopic crystalline regions surrounded by amorphous polyaniline and not by intermolecular hopping or molecular scale disorder. Two independent approaches yield an average size of 8 nm for the metallic regions in polyaniline with 3D extended electron wave functions. The barrier width is estimated to be 1.6 nm. The crystalline metallic regions with an amorphous shell correspond to the primary particles which were found in morphological studies.

New Insight into Organic Metal Polyaniline Morphology and Structure

Polymers (2010)

Bernhard Weßling

Polyaniline is known to be a true metal, though a nanometal. Previous experimental and theoretical evidence is reviewed. Two important structural features are presented, which have not publicly been discussed so far: (a) The formation of complexes between polyaniline and metals (Cu, Fe, Zn, In, etc.) which are crucial for most practical applications of the organic metal, polyaniline; and (b) a model for the polyaniline chain structure within the smallest morphological unit, the roughly 10 nm primary particle.

STM investigations on primary particle morphology of polyaniline

Acta Polymerica (1993)

Bernhard Weßling Renate Hiesgen D Meißner

Abstract SEM investigation of polyaniline (PAni) layers showed that it is composed of around 10 nm small primary particles. This is in accordance with other earlier results.
