Nanostructured Polyaniline Sensors

Chemistry - A European Journal, 2004
AbstractThe conjugated polymer polyaniline is a promising material for sensors, since its conductivity is highly sensitive to chemical vapors. Nanofibers of polyaniline are found to have superior performance relative to conventional materials due to their much greater exposed surface area.

Polyaniline

2009
Abstract Major Applications Polyaniline is finding widespread use in novel organic electronic applications such as light emitting diodes (LED), electroluminescence, metallic corrosion resistance, organic rechargeable batteries, biological and environmental sensors, composite structures, textile structures for specialized applications or ...

Electrorheology of polyaniline, carbonized polyaniline, and their core–shell composites

Materials Letters, 2013
In the search for a new electrorheological system, silicone oil suspensions of polyaniline base, carbonized polyaniline base, and core–shell particles of carbonized polyaniline base coated with polyaniline base have been investigated. The conversion of the materials was followed by Raman spectroscopy.

Understanding the Protonation of Polyaniline and Polyaniline–Graphene Interaction

The Journal of Physical Chemistry C, 2012
The stability and electronic structure of (protonated) polyaniline (PANI) and PANI–graphene composite are systematically studied using density-functional simulations. The protonation of PANI is a spontaneous exothermic reaction. It decreases the band gap of PANI and introduces shallow impurity states (ISs), both of which tend to increase the ...

Blue emitting polyaniline

Chemical Communications, 2006
A family of stable polyaniline (PANI) derivatives exhibiting deep blue photoluminescence (PL) has been prepared. The synthetic strategy provides a unique way to functionalize the PANI backbone.

Patterned polyaniline & carbon nanotube–polyaniline composites on silicon

Soft Matter, 2009
Atomic force anodisation lithography has been used to create patterned silicon oxide nanostructures on a p-type silicon (100) substrate. Modification of these oxide nanostructures either by acid treatment or self assembly of 3-aminopropyltriethoxysilane yields a chemically heterogeneous surface containing hydrophilic and hydrophobic regions allowing ...

Self-assembly of polyaniline nanowires into polyaniline microspheres

Materials Letters, 2011
Abstract High quality microspheres self-assembled from nanowires of polyaniline (PANI) are prepared by a self-assembly process using ammonium peroxydisulfate as oxidant in aqueous solution. The microspheres of about 2.6 μm average diameter are composed of uniform nanowires with 40–60 nm in diameter. The formation process of PANI microsphere indicates

Metallic transport in polyaniline

Nature, 2006
Despite nearly three decades of materials development, the transport properties in the 'metallic state' of the so-called conducting polymers are still not typical of conventional metals. The hallmark of metallic resistivity--a monotonic decrease in resistivity with temperature--has not been obtained at temperatures over the full range below room ...

Thin film polyaniline-polyaniline electrochemical cells

Journal of Applied Electrochemistry, 1993
Electrodeposited polyaniline (PANT) in the emeraldine oxidation state was used as the electrodes of open rechargeable cells containing 1 m HClO4 as the electrolyte. The cells could be charged at very high hourly rates to 85% of the redox charge in the leucoemeraldine-emeraldine transition of the polymer.
