Moderately compressed exfoliated graphite (CEG) leads to highly porous graphite “foams” or matrices which have numerous actual and potential applications. The graphite/salt composite materials considered here for high temperature energy storage applications, as due to its superior heat conduction and thermal storage characteristics, are manufactured by uniaxial compression of a mixture of salt ...

In this article, a facile way for the doping of graphene and derivatives with silver nanoparticles at different Ag ratios is described. were formed directly on surface two substrates dispersed in dimethylformamide by reduction cations NaBH4. A few layered nanosheets (FLG) produced from graphite reduced oxide functionalized amino arylsulfonates (f-rGO) used as substrates. The final graphene/Ag n...

The adsorption behavior of hydrogen for synthesized graphitic carbon nitride (g-C3N4) and graphene oxide nanosheets was compared. The structure of the prepared g-C3N4 and graphene oxide samples were studied using TEM, FT-IR spectroscopy and surface area analysis. Textural results of the prepared nanosheets show that the surface area, total pore volume, and average internal diameter of g-C3N4 an...

Graphene is one of the most important forms carbon. Due to its exceptional physical, chemical, and mechanical properties, it’s used in different fields such as electronic, energy storage, medical applications. Therefore, production graphene large quantities, at a low cost, high quality, has become critical. Using graphite powder, few layers sheets were prepared via series exfoliation methods. d...

Graphite oxide (GO) is a well known material since the middle of the XIX century. In the latest years it has attracted a renewed fame and interest as a precursor for a cheap large-scale production of graphene. Indeed, GO conserves the layered structure of graphite with an expanded interlayer distance that facilitates exfoliation, a subsequent reduction yields a material whose properties are ver...

Nanocomposites based on poly (phenylene sulfide) (PPS) and expanded graphite (EG) or ultrasonicated EG (S-EG) were prepared by melt blending. Morphologies of the nanocomposites were examined using both SEM and TEM. Electrical conductivity and thermal stability of PPS were notably enhanced by the introduction of EG. The percolation threshold values are 1 wt% (S-EG) and 2 wt% (EG) for PPS/S-EG an...

Two-dimensional (2D) transition metal dichalcogenide (TMD) nanosheets exhibit remarkable electronic and optical properties. The 2D features, sizable bandgaps and recent advances in the synthesis, characterization and device fabrication of the representative MoS2, WS2, WSe2 and MoSe2 TMDs make TMDs very attractive in nanoelectronics and optoelectronics. Similar to graphite and graphene, the atom...

In this study, free-standing expanded graphite chitosan (EG-chitosan) nanocomposite films have been prepared using a novel green and simple preparation method, starting from a commercial expandable graphite (GIC). The in situ exfoliation of GIC by a solvent-free sonication method was monitored as a function of the process parameters using X-ray diffraction (XRD), transmission electron microscop...
