Journal of Polymer Science Part A: Polymer Chemistry, 1988
AbstractFlexible polyaniline having excellent mechanical properties (e.g., elongation at break = 41% and tensile strength = 1.8 kg cm−2) was prepared by electrochemical reduction of ordinary polyaniline in organic solvents. The flexibility is directly related with the polymer morphology which was definitely affected by the nature of electrolyte anion ...

Journal of Power Sources, 2017
Polyaniline (PANI) has been widely used for the energy storage applications either as a conducting agent or directly as an electroactive material due to the tunable pseudocapacitive performance owing to its various oxidation states. Although PANI supercapacitors are known for over three decades, immediate attention has been paid just over the past few ...

Inkjet Printable Polyaniline Nanoformulations
Langmuir, 2007Aqueous 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, 1999Polyaniline / 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, 2011Abstract 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, 1994AbstractAniline 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, 2006Despite 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, 1989Abstract 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, 2009Conducting 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, 2011Abstract 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 ...
