‘Polyaniline’: Protonic acid doping of the emeraldine form to the metallic regime
J. C. Chiang,Alan G. MacDiarmid +1 more
TL;DR: The emeraldine base form of polyaniline, which consists of equal numbers of reduced and oxidized repeat units, is doped to the metallic conducting regime by aqueous 1 M HCl as mentioned in this paper.
Journal ArticleDOI
Polyaniline: a new concept in conducting polymers
TL;DR: In this paper, the emeraldine oxidation state of polyaniline was converted from an insulator to a metal by treatment with 1M aqueous HCl to form the corresponding salt, emeraldines hydrochloride.
Journal ArticleDOI
“Polyaniline”: Interconversion of Metallic and Insulating Forms
Alan G. MacDiarmid,J. C. Chiang,Marc Halpern,W. S. Huang,Shao-Lin Mu,L. D Nanaxakkara,Somasiri Wanqun Wu,Stuart I. Yaniger +7 more
TL;DR: In this paper, the qulnoid-benzenoid-diimine form is doped by dilute aqueous protonic acids to the metallic regime to give the corresponding iminium salt.
Book ChapterDOI
Polyaniline: Synthesis and Characterization of the Emeraldine Oxidation State by Elemental Analysis
TL;DR: In this paper, detailed experimental procedures are given for the chemical synthesis from aniline of analytically pure emeraldine hydrochloride, a highly conducting polymer derived from polyaniline, which contains equal numbers of oxidized and reduced repeat units, the non-protonated base form of which has the composition.
Journal ArticleDOI
Polyaniline: Protonic Acid Doping to the Metallic Regime
TL;DR: In this article, the quinoid-benzenoid-diimine form of polyaniline is doped by dilute aqueous protonic acids to the metallic regime to give the corresponding iminium salt.
