graphene oxide can be adsorbed at the air-water interface of the aqueous solution by diffusion, Gibbs monolayers, or by spreading on a clean water subphase resulting in aLangmuir film. This review is intended to provide information on the importance of controlling the chemical composition, structur...
The preparation method comprises the following steps: adding a graphene oxide aqueous solution into an ionic liquid solution so as to obtain a blended solution of graphene oxide and ionic liquid, carrying out suction filtration on the blended solution, and draining to obtain the graphene oxide and...
the graphene was highly aggregated and presented a blocky structure15. In general, the sheet architecture is related to the graphene oxide structure, while the spherical structure attributed to SiO2. TEM analysis
graphene oxide (GO) based gas separation membranes are of interest due to their selective barrier properties. However, maintaining selectivity without sacrificing permeance is still challenging. Herein, we described the preparation and characterization of nanoscale ...
The presence of highly conductive CNTs in a graphene oxide (GO)/CNT hybrid film not only prevented the restacking of graphene nanosheets but also allowed for effective electrochemical reduction of the GO, leading to a superb rate capacitance of 90 F g−1 at a current density of 100 A g...
(f) The schematic diagram of reducing graphene oxide to develop reduced graphene oxide [96]. (g) Epitaxial growth of graphene on a SiC wafer [97]. (h) Schematic of flash Joule heating (FJH) [79]. CVD technique provides many opportunities such as low cost, easy film transferring, ...
film in n-hexadecane lubricating oil, Zhang et al. performed pin-on-disk tests and molecular dynamic studies. It was found that the adsorption of the lubricant could be increased by adding graphene, and shear stresses on the surface were reduced [4]. Wu et al. studied graphene oxide ...
The liquid dispersion may then be used to create a thin film on the substrate of your choosing. These thin-films have a range of applications, such as transistors, solar cells, and energy storage devices. WS2 solution can also be used in composite materials. ...
Graphene oxide (GO) flakes dissolved in water can spontaneously form liquid crystals. Liquid crystallinity presents an opportunity to process graphene materials into macroscopic assemblies with long-range ordering, but most graphene electronic functionalities are lost in oxidation treatments. Reduction of GO...
Single-layer Graphene oxide (GO) and Carboxyl graphene (CXYG) were purchased from ACS Material, LLC. (Ames, IA, USA). GO was prepared by modified Hummers´s method and exfoliated as described in Allister et al. (2007) and supplied as thin film with a single layer ratio of ~ 99...
