In this paper, we demonstrate the preparation of a flexible poly (3,4-ethylenedioxythiophene) -poly (styrenesulfonate)/reduced graphene oxide (PEDOT-PSS/RGO) film with a layered structure via a simple vacuum filtered method as a high performance electrochemical electrode. The PEDOT-PSS/RGO films are characterized by scanning electron microscopy (SEM), X-ray diffraction, Raman spectroscopy, and ...

We demonstrate a new light-responsive poly(N-isopropylacrylamide) (PNIPAAm) hydrogel nanocomposite incorporating glycidyl methacrylate functionalized graphene oxide (GO–GMA) instead of metallic nanoparticle fillers. GO–GMA is synthesized by esterification with glycidyl methacrylate. GO–GMA incorporated hydrogels are synthesized by photopolymerization of NIPAAm including 4-dimethylaminopyridine ...

In this work, plasmon characteristics of nanocomposite materials based on graphene, graphene oxide, and silver nanoparticles have been studied. The effective dielectric constant absorption coefficient the nanocomposites graphene-silver oxide – depending concentration size calculated. A change in filling factor by 5 percent leads to significant changes both real imaginary parts material. pronoun...

A novel 3D hierarchical nanocomposite of vertically aligned porous FeP nano-wires on reduced graphene oxide is prepared as a demonstration of constructing an efficient hydrogen evolution catalyst. Extension of this nanostructuring strategy to other functional nanocomposites by combining different dimensional nanomaterials is attractive.

A unique nanocomposite was constructed by grafting an aptamer on graphene and used as a label-free biosensor for thrombin sensing, showing good selectivity, a low detection limit of 0.45 fM and high sensitivity, with a linear response up to 100 fM.

Different nanocomposites between reduced graphene oxide (rGO) and Ni(OH)2 nanoparticles were synthesized through modifications in the polyol method (starting from graphene oxide (GO) dispersion in ethylene glycol and nickel acetate), processed as thin films through the liquid-liquid interfacial route, homogeneously deposited over transparent electrodes and spectroscopically, microscopically and...

Composites of the nano‐sized perovskite‐type oxide of LaMnO3 and multi‐walled carbon nanotubes (MWCNTs) were synthesized in a single step using the sol‐gel method. Their photocatalytic activities for the degradation of various water‐soluble dyes under visible light were evaluated. The prepared samples were characterized by thermogravimetry analysis, scanning electron microsc...

We report the optimized synthesis and electrochemical characterization of a composite of few-layered nanostructured MoS2 along with an electroactive metal oxide BiVO4. In comparison to pristine BiVO4, and a composite of graphene/BiVO4, the MoS2/BiVO4 nanocomposite provides impressive values of charge storage with longer discharge times and improved cycling stability. Specific capacitance values...
