Abstract We have obtained conducting inks through the hybridization of indium tin oxide (ITO) and polypyrrole. Different conductive were at different ITO loadings. The zeta potentials polypyrrole-ITO investigated as functions pH solution. exhibited zero potential approximately = 5, varied with solution, which also significantly depended on range. Thermogravimetric analysis was performed to inve...

A mechanism for the reduction of aqueous nitrate with metal-free polypyrrole (PPy) is proposed. The activity and selectivity polymer has been compared to those metal catalysts supported on polypyrrole, activated carbon or titania (TiO2). role formic acid (FA) hydrogen (H2) as reductants, dioxide (CO2) buffer solution discussed performance PPy by itself. ion-exchange redox properties are strongl...

The organic polymer known as Polypyrrole (Ppy) is synthesized when pyrrole monomers are polymerized. Excellent thermal stability, superior electrical conductivity, and environmental stability all characteristics of Polypyrrole. Chemical oxidative polymerization was used to synthesize Ppy using Ferric chloride (FeCl3) an oxidizing agent surfactant CTAB in aqueous solution. Oxidant varied differe...

The electrochemical coating technique was used for the preparation of a polypyrrole coating on a stainless-steel wire, and applied as a fibre for solid phase microextraction (SPME). The polypyrrole fibre was employed for analyzing four volatile aliphatic amines (ethylamine, propylamine, butylamine and pentylamine) in water by headspace SPME using gas chromatography-flame ionization detection (G...

Laser-induced graphene (LIG) films were synthesized by line-by-line scanning of cw CO 2 laser focused radiation on the surface industrial polyimide film as a result pyrolysis its near-surface layer. The structure material is shown to be heterogeneous in thickness Raman spectroscopy. results study effect power and distance between lines specific electrical capacitance c aqueous solution sulfuric...

Ultrahigh surface area carbons (3000 – 3500 m g) have been obtained via chemical activation of polypyrrole with KOH. The carbon materials exhibit large pore volumes (up to ~2.6 cm g) and possess two pore systems; one of pores in the micropore range (~ 1.2 nm) and the other in the small mesopore range (2.2 – 3.4 nm). Some carbons also possess a significant proportion of 0.6 nm pores. Tunning of ...

By taking advantage of bacterial extracellular electron transfer behavior, a facile method was developed to fabricate oriented polypyrrole micro-pillars (PPy-MP) with nanoscale surface roughness. Microbes acted as a living conductive template on which PPy was in situ polymerized. The as-prepared PPy-MP exhibit the distinctive underwater low adhesive superoleophobicity which is attributable to t...

Potentiometric sensing and electrochemical recycling of cadmium ion have been demonstrated over chemical interactive electrically conducting bio nanocomposite film comprised zinc oxide, sodium alginate, polypyrrole (ZnO/SA-g-PPy) using...

Polypyrrole (PPy) was synthesized using the Chemical polymerization technique Ammonium per sulphate (APS), as an oxidant and Plasma Polymerization technique. The polypyrrole by chemical oxidation method in black amorphous powder form. In polymerization, thin films were created on a glass plate. Structural morphological properties of polymer studied FTIR, SEM and. X-ray diffraction. electrical c...
