Polyimide-graphene nanosheet composite electrodes are rigid and dense and, therefore, exhibit moderate electrochemical properties. The properties of polyimide-graphene were remarkably improved by creating voids in the followed insertion nickel oxide into composites. Nickel particles electrodeposited onto porous graphene/poly(amic acid) composite, containing poly (acrylic resin). hybrid was then...

A series of polyethylene glycol (PEG) functionalized graphene sheet hybrid materials (FGHMs) have been successfully synthesized via ester linkages. Interestingly, our products can be dispersed in both polar/protic solvents and nonpolar/nonprotic ones, which differ significantly from previously reported systems and are of great value in the wide-spread application of these "carbon nanosheet" bas...

Through a catalyst- and transfer-free process, we fabricated indium tin oxide (ITO)-free organic solar cells (OSCs) using a carbon nanosheet (CNS) with properties similar to graphene. The morphological and electrical properties of the CNS derived from a polymer of intrinsic microporosity-1 (PIM-1), which is mainly composed of several aromatic hydrocarbons and cycloalkanes, can be easily control...

The silicon nanostructure is a promising candidate for an anode of Li-ion batteries due to its high theoretical capacity. In this work, we have demonstrated the scalable synthesis of Si nanosheets from natural sand by magnesiothermic reduction, and suggested a new formation mechanism for Si nanosheets. In the suggested mechanism, an Mg₂Si intermediate phase was formed at an early stage of the r...

Shape memory nanocomposites are excellent smart materials which can switch between a variable temporary shape and their original upon exposure to external stimuli such as heat, light, electricity, magnetic fields, moisture, chemicals, pH, etc. Numerous nanofillers have been introduced in polymers carbon nanotubes, graphene, nanodiamonds, nanofibers, Among nanocarbons, graphene has attracted res...

The adsorption of choline benzoate ([CH][BE]) ionic liquid (IL) on the surface of different hexagonal nanosheets has been studied using Density Functional Theory (DFT) methods. For this, the interaction mechanism, binding energies and electronic structure of [CH][BE] ionic liquid on four types of nanosheets, i.e., graphene, silicene, germanene and boron-nitride, were estimated and compared. The...

The viscosity of polydispersed graphene nanosheet (5 nm–1.5 lm) suspensions (GNS) and its behavior with temperature and concentration have been experimentally determined. A physical mechanism for the enhanced viscosity over the base fluids has been proposed for the polydispersed GNSs. Experimental data reveal that enhancement of viscosity for GNSs lies in between those of carbon nanotube suspen...

Novel reduced graphene oxide (RGO) nanosheet/PtPd nanowire hybrids were prepared by a mild wet chemical approach. Uniform Pt nanowire arrays are successfully supported on functionalized RGO nanosheets with Pd nanoparticles as growing seeds. The whole deposition process was achieved in aqueous solution at room temperature. TEM and HRTEM analysis indicated the single-crystal feature of the Pt nan...
