cofe2o4 magnetic nano particles (mnps) were synthesized by an efficient method in aqueous medium with the particle sizes of about 20-50 nm. then, a hybrid nanocomposite of polyaniline (pani)-cofe2o4 mnps has been electrodeposited directly on a stainless steel wire by the potentiostatic method. microscopic images of electrodeposited pani and pani-cofe2o4 nanocomposite coatings were obtained by s...

electrically conducting nanofiber mats of polyaniline/copolyacrylonitrile (pani/ pan) blend in nmp were successfully fabricated using electrospinning technique. morphology and diameter of the nanofibers were studied by scanning electron microscope. structural characteristics of the electrospun nanofibers were examined using differential scanning calorimetry, fourier transform infrared spectrosc...

The surface of oxidant crystals facilitates the simultaneous synthesis and morphogenesis of conductive polymer materials. Oxidant crystals as a condensed phase of the oxidative agent induce the formation of the conductive polymer nanoparticles and their accumulated films.

Our paper reviews the use of conductive polymer composite materials in various applications for semi conductive, static-dissipative, anti-corrosive, electromagnetic interference (EMI) shielding and stealth composite coatings. The composite consists of conductive fillers and the insulating polymer network. The composite becomes electrically conductive as the filler content exceeds a certain crit...

Electrode used in lithium-ion battery is invariably a composite of multifunctional components. The performance of the electrode is controlled by the interactive function of all components at mesoscale. Fundamental understanding of mesoscale phenomenon sets the basis for innovative designing of new materials. Here we report the achievement and origin of a significant performance enhancement of e...

Conductive biodegradable materials are of great interest for various biomedical applications, such as tissue repair and bioelectronics. They generally consist of multiple components, including biodegradable polymer/non-degradable conductive polymer/dopant, biodegradable conductive polymer/dopant or biodegradable polymer/non-degradable inorganic additives. The dopants or additives induce materia...

A redox exchange mechanism between potassium perruthenate (KRuO4) and the functional groups of selected polymers is used here to induce RuO2 into and onto conductive polymer nanowires by simply soaking the polymer nanowire arrays in KRuO4 solution. Conductive polymer nanowire arrays of polypyrrole (PPY) and poly(3,4-ethylenedioxythiophene) (PEDOT) were studied in this work. SEM and TEM results ...

This paper introduces a technique of inducing bulk conductivity in a polymer. The technique uses coiled copper ‘cells’ embedded into a polymer during fabrication which can subsequently create highly redundant series-parallel networks. The preceding body of work aimed to improve the conductivity of non-conducting polymers by embedding particulates (of metal, carbon, etc.) into the polymer, or by...

1. General Introduction Conductive polymer composite materials deserve interest in several application fields [1]. A composite consisting of conductive fillers and an insulating polymer becomes electrically conductive as the filler content exceeds a certain critical value, which is generally attributed to percolation phenomenon. These percolation threshold values for the particular polymer comp...
