Charge transport of the mesoscopic metallic state in partially crystalline polyanilines
Jinsoo Joo,Jinsoo Joo,S.M. Long,Jean-Paul Pouget,E.J. Oh,Alan G. MacDiarmid,Arthur J. Epstein +6 more
TL;DR: In this article, an inhomogeneous disorder model was proposed for a physically cross-linked polyaniline system, where ordered (crystalline) regions, described by three-dimensional metallic states, are connected through amorphous regions of polymer chains where one-dimensional disorder-induced localization is dominant.

Charge transport properties of fully-sulfonated polyaniline
TL;DR: In this paper, the authors present a charge transport study of a newly prepared fully sulfonated polyaniline IN-SPAN with the sulfur-to-nitrogen (S/N) ratio ∼ 1.0.

Li+ doping-induced localization in polyaniline
TL;DR: In this paper, LiCl dopes the emeraldine base (EB) form of polyaniline and produces polyanILine with unusual properties, such as low DC conductivity, low dielectric constant, rapid decrease of the oscillator strength to zero in the infrared, low magnetic susceptibility dominated by a weak Curie component, broad EPR linewidth and predominantly Gaussian lineshape of the EPR signal.

Optical and EPR studies of LiCl pseudodoping of emeraldine base
A. Saprigin,R. S. Kohlman,S.M. Long,Keith R. Brenneman,Arthur J. Epstein,Marie Angelopoulos,Y. H. Liao,W. Zheng,Alan G. MacDiarmid +8 more
TL;DR: In this article, the pseudodoping of the emeraldine base (EB) form of polyaniline with protonic acids with Li + ions was reported, based on defect states in the bandgap and associated spins for EB processed with LiCl.

Aggregation and interchain “self” doping in emeraldine base
S.M. Long,Keith R. Brenneman,A. Saprigin,R. S. Kohlman,Arthur J. Epstein,Marie Angelopoulos,S.L. Buchwalter,A. Rossi,W. Zheng,Alan G. MacDiarmid +9 more
TL;DR: In this article, the authors report gel permeation chromatography, electron paramagnetic resonance and optical absorption measurements on the emeraldine base (EB) form of polyaniline synthesized using different oxidant and aniline ratios in the range of 0.25 to 1.0.
