For the first time, a complex formed by polyaniline (in its organic metal form) and silver has been deposited on copper in nanoparticulate form. When depositing on Cu pads of printed circuit boards it efficiently protects against oxidation and preserves its solderability. The deposited layer has a thickness of only nominally 50 nm, containing the Organic Metal (conductive polymer), polyaniline,...

Chemical oxidative polymerization of aniline in dilute aqueous acids using an ammonium peroxydisulfate oxidant proceeds via the intermediacy of large, colorless aggregates that act as ‘seeds’ in orchestrating the overall morphology of the product polyaniline. Observed for the first time by continuously monitoring the polymerization by static and dynamic light-scattering (LS) measurements, these...

Electrocatalytic oxidation of methanol on Pt modified polyaniline electrodes was investigated with the aim of developing highly active composite electrodes for direct methanol fuel cells. Cyclic voltammetry and chronoamperometry were used to evaluate the catalytic activity in sulfuric acid solutions containing methanol. Pt / polyaniline modified carbon electrodes showed higher catalytic activit...

Nucleic acid sensor based on polyaniline has been fabricated by covalently immobilizing double stranded calf thymus (dsCT) DNA onto perchlorate (ClO4 ) doped polyaniline (PANI) film deposited onto indium-tin-oxide (ITO) glass plate using 1-(3-(dimethylamino) propyl)3-ethylcarbodiimide hydrochloride (EDC)/N-hydroxyl succinimide (NHS) chemistry. These dsCT-DNA-PANI/ITO and PANI/ITO electrodes hav...

Polyaniline composite films incorporated with aligned multi-walled carbon nanotubes (MWCNTs) are synthesized through an easy electrodeposition process. These robust and electrically conductive films are found to function as effective electrodes to fabricate transparent and flexible supercapacitors with a maximum specific capacitance of 233 F/g at a current density of 1 A/g. It is 36 times of ba...

The rational design of efficient and stable carbon-based electrocatalysts for oxygen reduction evolution reactions is crucial improving energy density long-term stability rechargeable zinc-air batteries (ZABs). Herein, a general controllable synthesis method was developed to prepare three-dimensional (3D) porous carbon composites embedded with diverse metal phosphide nanocrystallites by interfa...

Polyaniline is one of the most common electrode materials for supercapacitors. The morphology polyaniline directly affects properties polyaniline. In this paper, a new method preparing hollow nanospheres described. Polyaniline-S with solid and structures are successfully synthesized by hydrothermal method, through varying amounts catalyst oxidant. prepared have uniform particle size, smooth sur...
