In this report, a novel chemical synthesis of polyaniline/gold nanocomposite is explored using ionic liquid (IL) 1-Butyl-3-methylimidazolium hexafluorophosphate. The direct chemical synthesis of polyaniline/gold nanocomposite was initiated via the spontaneous oxidation of aniline by AuCl(4) (-) in IL. A nearly uniform dispersion of polyaniline/Au particles with a diameter of 450 ± 80 nm was pro...

Hydroxyapatite (HAp) nanoparticles synthesized via microwave irradiation. Polypyrrole (PPy)/HAp nanocomposite was obtained using electropolymerization on nitinol (Ni) titanium (Ti) substrates. Fourier transform infrared was employed to characterize the nanocomposite formation. Electrochemical properties of the nanocomposite were investigated using polarization and electrochemical impedance spec...

The work presented here demonstrates using a novel, field-responsive nanocomposite based on shear thickening fluids (STFs) as responsive protective materials with superior damping and energy adsorption properties. Peak forces and accelerations measured using an instrumented Instron drop tower demonstrate that STF nanocomposite prototypes and impact foam taken from a commercial football helmet h...

Copper-based alloys are one of the most popular materials in power distribution, welding industry, hydraulic equipment, industrial machinery, etc. Among different methods for fabrication Cu alloys, mechanical alloying (MA) is major approach due to fact that this simple, inexpensive, suitable mass production, and has a high capacity homogeneous distribution second phase. However, prediction hard...

In this article, a facile strategy is developed to synthesize a nanocomposite containing both a rare earth doped upconversion nanoparticle (RE-UCNP) and gold nanoparticles (GNPs). Such a nanocomposite can serve as a dual-modal imaging agent for upconversion luminescence (UCL) imaging and photoacoustic tomography (PAT). High spatial resolution, 3-dimensional imaging of blood vessels could be ach...

Gamma-irradiation initiated polymerization was utilized to prepare polyacrylonitrile acrylamide nano-silica (P(AN-AM)-NS). Various analytical tools like XRD, FT-IR, SEM, TEM, and DTA TGA were used estimate the morphology, functional groups, structure of P(AN-AM)-NS nanocomposite. The ability nanocomposite remove Cs(I), Pb(II), Cd(II), Sr(II), Cu(II) ions from multi-component system evaluated by...

In this article, preparation of polypyrrole and its nanocomposites as adsorbents werediscussed and the capability of separation of copper ions from aqueous solution were studied.Polypyrrole was prepared by chemical oxidative polymerization method of pyrrole usingFeCl3 as an oxidant. The removal of Cu (II) was investigated using PPy, PPy/TiO2 andPPy/TiO2/DHSNa nanocomposites. The products were i...

In this work, new samples of PVA-TiO2/Cu nanocomposites were prepared via the casting method. The examined using different analytical methods. An XRD analysis showed semi-crystalline nature PVA polymer, as well showing a decrease in degree crystallinity structure result addition mixed nanoparticles. TEM images indicate spherical shape Cu NPs, with size ranging from 2 to 22 nm, and rectangular T...

The study describes an in situ green biosynthesis of zinc oxide nanocomposite using the seaweed Sargassum muticum water extract and hyaluronan biopolymer. The morphology and optical properties of the hyaluronan/zinc oxide (HA/ZnO) nanocomposite were determined by Fourier transform infrared spectroscopy, X-ray diffraction, field emission scanning electron microscopy, transmission electron micros...
