Polypyrrole (PPy) nanofibers have been fabricated on glassy carbon electrode (GCE) usingelectrochemical technique. Electropolymerization of pyrrole (Py) for the fabrication of PPy nanofiberswas occurred on GCE by applying a fixed potential of about 0.85 V for 120 sec in a mild basic solutioncontaining sodium carbonate and sodium perchlorate. In the mild basic media, the monomer, Py, isoxidized ...

Polypyrrole globules, nanofibers and nanotubes were activated by their carbonization at 650 °C in the 3:1 mass excess of molten potassium hydroxide argon. They have been compared with parent polypyrroles analogous samples obtained absence hydroxide. The yields after activation, 12–18 wt%, lower to carbonization, which exceeded 50 wt%. changes molecular structure are discussed on basis FTIR Rama...

It is demonstrated that it is possible to coat the individual fibers of wood-based nanocellulose with polypyrrole using in situ chemical polymerization to obtain an electrically conducting continuous high-surface-area composite. The experimental results indicate that the high surface area of the water dispersed material, to a large extent, is maintained upon normal drying without the use of any...

Different superhydrophilic polypyrrole nanostructures can be electrosynthezised in the presence of anions of weak acid (monohydrogenophosphate) and non-acidic anions (perchlorate) without the need for templates. Actually the type of nanostructures formed depends both on the concentration of anions at the electrode and on the interfacial pH. Depending on the anion composition of the pyrrole aque...

Metal Chalcogenides (MCs) have emerged as an extremely important class of nanomaterials with applications ranging from lubrication to energy storage devices. Here we report our discovery of a universal, ultrafast (60 seconds), energy-efficient, and facile technique of synthesizing MC nanoparticles and nanostructures, using microwave-assisted heating. A suitable combination of chemicals was sele...

A porous nanocomposite based on polypyrrole (PPy) and sodium alginate (SA) has been synthesized by easy, inexpensive, eco-friendly method. As prepared nanocomposite showed fibrillar morphology in transmission electron microscopic (TEM) analysis. The average diameter of ~100 nm for the nanofibers was observed from scanning electron microscopic (SEM) analysis. As prepared nanofiber, was investiga...
