Journal ArticleDOI
Studies on the Chemical Syntheses and on the Characteristics of Polyaniline Derivatives
TL;DR: In this article, the effect of substituent substitutions on the aniline ring leads to longer polymerization times and lower V, potential values, while the influence of the substituents on the V,, profile and on the polymer characteristics are rationalized in terms of steric and electronic effects.
Journal ArticleDOI
Photoelectron spectroscopy of iodine‐doped polyacetylene

TL;DR: In this paper, X-ray and ultraviolet photoelectron spectroscopy (XPS and UPS) were used in a study of the electronic structure of iodine-doped polyacetylene.
Journal ArticleDOI

TL;DR: Two types of artificial muscles that convert the chemical energy of high–energy-density fuels to mechanical energy are demonstrated that provide actuator stroke and power density comparable to those of natural skeletal muscle and generated stresses that are over a hundred times higher.
Journal ArticleDOI
Physical Characterization of Some Polyaniline, (øN)x
William R. Salaneck,Bo Liedberg,Olle Inganäs,R. Erlandsson,Ingemar Lundström,Alan G. MacDiarmid,M. Halpern,Nanayakkara L. D. Somasiri +7 more
TL;DR: In this article, the authors found that polyaniline (4oSN) exhibits a low energy absorption edge beginning near 1800 cm−1 (ca: 0.22 eV).
Journal ArticleDOI
Electrical conductivity of (SN)x

TL;DR: In this paper, the b-axis conductivity of polymeric sulfur nitride (SN) x from 4.2-300K was measured for samples having different polymerization times and a general increase in the conductivity was found with longer polymerisation times leading to room temperature conductivities 1200 −3700 (Ω-cm) −1 and resistance ratios 50 −205.
