Polyaniline nanoparticles were prepared using oxidation polymerization in micro-emulsion system. Sodium dodecyl sulphate was used as a surfactant which dissolved in hydrochloric acid giving the micellar solution. Potassium persulphate was used as an oxidant. The produced particles were spherical in shape with an average diameter of 15 nm as detected from the transmittance electron microscope im...

This paper presents the processing and characterization of electromagnetic radiation absorbing paints and sheets based on magnetic and dielectric materials dispersed in polymeric matrices. Two different paint formulations containing carbonyl iron and/or polyaniline, using polyurethane as matrix, were prepared. Silicone sheets were also produced with polyaniline conducting polymer as filler. Mea...

In recent years, developments of inorganic–organic hybrid materials on nanometer scale have been receiving significant attention due to a wide range of potential applications and high absorption in the visible part of the spectrum and high mobility of the charge carriers [1-3]. Conductive polymer with polyaromatic backbone including polypyrrole, polythiophene, polyaniline, etc. The received a g...

The adsorbent for both cationic and anionic dye based on cellulose polyaniline was prepared. Cellulose purified from sugarcane bagasse through the removal of hemicellulose lignin. Aniline polymerized in emulsion state presence ammonium persulfate as an initiator. results Fourier Transform Infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM) observation determination porosity confirm...

a nanocomposite of polyaniline (pani) with natural clinoptilolite (clino) was prepared by chemical oxidative polymerization of anilinium cations in the presence of clinoptilolite dispersion. the pani/clino nanocomposite was characterized using ftir, xrd and sem techniques as well as electrical conductivity measurement using four point probe technique. cyclic voltammetry analysis was used to inv...

   Hybrid polyaniline (PANI) based composites incorporating zinc sulfide (ZnS) nanoparticles (NPs) have been synthesized by using chemical oxidation technique. Schottky junction is constructed by depositing Polyaniline-zinc sulfide nanocomposite (PANI-ZnS NCs) on Au electrode. The results were compared with pure polyaniline. The I–V characteristics of the PANI-ZnS NCs hete...

The analysis of the structure and chemical state polyaniline/multi-walled carbon nanotube interface layer was carried out using both methods Near Edge X-Ray Absorption Fine Structure Photoelectron Spectroscopy. An photoelectron spectra showed an increase in content covalently bound chlorine, which may be due to functionalization nanotubes during polymer synthesis. spectrum shows two states chlo...

The path-breaking discovery of high conductivity in polyacetylene in 1977 by A. J. Heeger, A. G. MacDiarmid and H. Shirakawa opened up a whole new field of research, which won them the Noble prize in the year 2000. Since then the field of conducting polymers has undergone tremendous developments and a wide range of commercial applications have evolved. Conducting polymers have found application...
