“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.
Journal ArticleDOI
Polaron lattice in highly conducting polyaniline: Theoretical and optical studies.
Sven Stafström,Jean-Luc Brédas,Arthur J. Epstein,H. S. Woo,David B. Tanner,W. S. Huang,Alan G. MacDiarmid +6 more
TL;DR: In this paper, the authors present optical-absorption data together with band-structure calculations for the polaron lattice and bipolaron lattice for the highly conducting form of polyaniline, proton-doped polyemeraldine.
Journal ArticleDOI
Insulator-to-metal transition in polyaniline
Arthur J. Epstein,J. M. Ginder,Fulin Zuo,Richard W. Bigelow,H. S. Woo,David B. Tanner,A.F. Richter,W. S. Huang,Alan G. MacDiarmid +8 more
TL;DR: In this paper, the emeraldine base (EB) form of polyaniline can be varied from insulating ( σ −10 ohm −1 cm −1 ) through protonation.
Journal ArticleDOI
Polyaniline: Electrochemistry and application to rechargeable batteries
TL;DR: In this article, the authors showed that reversible electrochemical oxidation of the leuco-emeraldine base form of polyaniline in the pH range ≈ 1 to ≈ 4 occurs initially with no deprotonation to give the emeraldine salt; continued oxidation occurs with spontaneous deprotion to give pernigraniline base and a rechargeable battery employing analytically pure emeraldines base form as the cathode can be constructed.
Journal ArticleDOI
A two-dimensional-surface ‘state diagram’ for polyaniline
TL;DR: In this paper, the use of a two-dimensional surface is proposed to enable convenient and unambiguous description of the electrically conducting state of polyaniline-based polymers.
