Polyvinylpyrrolidone/polyaniline emeraldine salt (PVP/PANI) with additives (TiO2, ZnO, NaCl, and Na2SO4) was synthesized via oxidative in situ polymerization. Because of using PVP/PANI as a protective membrane layer and its applications in an electrical device, we investigated the mechanical and rheological properties of PVP/PANI and other composites in orde...

Suspensions of polyaniline-coated latex particles 13 μm in diameter showed the integer-fold voltammetric currents at the microelectrode of which size was similar to the diameter of the particles. The currents did not vary with concentrations of polyaniline particles but varied accidentally with each voltammetric run. They were caused by the reduction of a few polyaniline particles adsorbed on t...

LiV3O8-polyaniline nanocomposites have been synthesized via chemical oxidative polymerization directed by the anionic surfactant sodium dodecyl benzene sulfate. The polyaniline particles are uniformly coated on the LiV3O8 nanorods. The composite with 12 wt. % polyaniline retains a discharge capacity of 204 mAh g after 100 cycles and had better rate capability (175 mAh g at 2 C and 145 mAh g at ...

One dimensional polyaniline nanowire is an electrically conducting polymer that can be used as an active layer for sensors whose conductivity change can be used to detect chemical or biological species. In this review, the basic properties of polyaniline nanowires including chemical structures, redox chemistry, and method of synthesis are discussed. A comprehensive literature survey on chemires...

The path-breaking discovery of high conductivity in polyacetylene in 1977 by A. J. Heeger, A. G. MacDiarmid and H. Shirakawa opened up a whole new field of research, which won them the Noble prize in the year 2000. Since then the field of conducting polymers has undergone tremendous developments and a wide range of commercial applications have evolved. Conducting polymers have found application...

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 ...

In the field of inherently conducting polymers, polyaniline (Pani) has elicited tremendous interest due to its promising electrical properties and unique redox tunability. Synthetic routes involving the use of polyelectrolytes have significantly improved the processability of polyaniline. Recently, a template guided synthesis catalyzed by an enzyme, horseradish peroxidase (HRP), has provided a ...

Friction Nanolithography (FRNL) is used to fabricate polyaniline nano-wire on a flexible, insulating, and highly transparent substrate. FRNL uses SPM tip to scratch the substrate to form a trench with higher friction force. Polyaniline nano-wire is selectively deposited on the trench. Sub-100 nm polyaniline wire is fabricated based on FRNL.

Stabilizer-free polyaniline nanofiber aqueous colloids were obtained by the direct dispersing of polyaniline nanofiber prepared in the presence of β-cyclodextrin. The polyaniline nanofiber, the diameters of which are between 80 and 100 nm, can be steadily dispersed in near neuter (pH=6.5) aqueous solution for about 60 days without any steric or electrostatic stabilizer. © 2007 Elsevier B.V.
