8 Abstract Graphene is a material with extraordinary properties. Its mechanical and electrical properties are unparalleled but the difficulties in its production are hindering its breakthrough in on applications. Graphene is a two-dimensional material made entirely of carbon atoms and it is only a single atom thick. In this work, properties of graphene and graphene based materials are described...

SnO2/nitrogen-doped graphene nanohybrids have been synthesized by an in situ hydrothermal method, during which the formation of SnO2 nanocrystals and nitrogen doping of graphene occur simultaneously. The as-prepared SnO2/nitrogen-doped graphene nanohybrids exhibit enhanced electrochemical performance for sodium-ion batteries compared to SnO2/graphene nanocomposites. A systematic comparison betw...

We report the synthesized and preparation of graphene oxide (GO) nanocomposite functionalized with polyvinyl alcohol (PVA) with different concentration of graphene oxide 0, 1, 1.5, 2, 2.5, 3, 3.5 and 4% weight. This synthesized confirmed by FT-IR. The electrical conductivity of the all nanocomposite was measured at 25°C for all samples and the resulted showed electrical conductivity ...

despite the great potential of graphene as a nanofiller, achieving homogeneous dispersion remains the key challenge for effectively reinforcing polyolefin (such as polyethylene (pe) and polypropylene (pp)) nanocomposites. therefore, in this research, we report a facile combined in situ polymerization and masterbatch method for fabricating pp/reduced graphene oxide (rgo) nanocomposites. in the p...

abstract the graphene–chitosan composite film modified glassy carbon electrode was fabricated and used to determine amlodipine besylate. in 0.1 m ph 7.3 phosphate buffer solutions, the redox peak currents of amlodipine besylate increased significantly at graphene–chitosan composite film modified glassy carbon electrode compared with bare electrode and chitosan modified glassy carbon electrode, ...

Graphene-based nanocomposites are newly emerged materials with a wide range of applications such as in supercapacitors electrode. The high conductivity and ability for passing electric current, makes Graphene an appropriate new item to be used in cells. Electroactive transition metal oxides, owing fast reversible redox pairs, are used to store electrical charge. Furthermore, the Graphene/NiO na...

The formation of moiré superstructures between graphene and its underlying substrate has attracted significant attention because it significantly influences the morphology and properties of graphene. Through the density functional theory (DFT) calculations conducted on graphene/Re(0001) and graphene/Ir(111) moiré superstructures, we found that in contrast to the strain-driven moiré superstructu...
