Inkjet Printable Polyaniline Nanoformulations

Langmuir, 2007
Aqueous polyaniline (PANI) nanodispersions doped with dodecylbenzenesulfonic acid (DBSA) were synthesized and successfully inkjet-printed using a piezoelectric desktop printer. This paper examines the optimization and characterization of the nanoparticulate formulation for optimal film electrochemistry and stability.

Electrochemical Behaviors of Polyaniline / Polyaniline-sulfonic Acid Composites

Synthetic Metals, 1999
Polyaniline / anionic-polymer composites are important for battery applications due to the cation-exchanging property. Electroactive poly-aniline-2-sulfonic acid (poly-ASA) was used instead of conventional electroinactive sulfonated polymer. Polyaniline / poly-ASA composite was prepared by electrochemical dopant exchange.

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

Polyaniline dispersions 4. Polymerization seeded by polyaniline particles

Acta Polymerica, 1994
AbstractAniline hydrochloride was polymerized in water and in 1 M hydrochloric acid by oxidation with ammonium persulfate. The macroscopic precipitation of polyaniline was prevented by the presence of poly(vinyl alcohol). The change of pH occurring during the reaction were recorded. Their relation to color transitions is discussed.

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 ...

Electrical properties of polyaniline and substituted polyaniline derivatives

Synthetic Metals, 1989
Abstract Polyaniline and substituted polyaniline derivatives which the ortho position hydrogen is substituted with CH3, OCH3 and Cl are studied. Both protonic acid doping (i.e. the addition of protons to the polymer chain without changing the number of electrons in the chain) and the acceptor doping (i.e., the number of electrons in the polymer chain

Conducting carbonized polyaniline nanotubes

Nanotechnology, 2009
Conducting nitrogen-containing carbon nanotubes were synthesized by the carbonization of self-assembled polyaniline nanotubes protonated with sulfuric acid. Carbonization was carried out in a nitrogen atmosphere at a heating rate of 10 degrees C min(-1) up to a maximum temperature of 800 degrees C.

Thin polyaniline and polyaniline/carbon nanocomposite films for gas sensing

Thin Solid Films, 2011
Abstract We have studied the gas sensing properties of five polyaniline-based materials—thick and thin PANI films, nanocomposite PANI/MWNT and PANI/SWNT films, and PANI nanogranules embedded in a polyvinylpyrrolidone matrix. The films (except for the latter) were deposited within the induction period of the polymerization process on gold ...

Layered polyaniline/graphene film from sandwich-structured polyaniline/graphene/polyaniline nanosheets for high-performance pseudosupercapacitors

J. Mater. Chem. A, 2014
Binder-free layered graphene/polyaniline composite supercapacitor film was prepared by an environmentally friendly route. It exhibited 384 F g−1 at 0.5 A g−1 and 84% capacitance retention over 1000 cycles.

Thermal behavior of polyaniline films and polyaniline–polystyrene blends

Journal of Applied Polymer Science, 2002
AbstractIn this article, a study of the thermal behavior of polyaniline films and polyaniline–polystyrene blends is presented. Transport measurements (electrical conductivity and thermoelectric power) at high temperature and thermogravimetric analysis show that an irreversible degradation is observed near 450 K for films doped with DiOHP and near 500 K
