Investigation of graphene oxide nanosheets dispersion in water based on solubility parameters: a molecular dynamics simulation study

Abstract

The solubility parameters of GO were calculated as functions of both temperature and number of layers.

Organic sensitization of graphene oxide and reduced graphene oxide thin films for photovoltaic applications

“…The basal spacing is increased as compared to the graphite (raw) due to the incorporated oxygen functional groups and the resulting peak is shifted to the lower diffraction degree. In other words, this broad peak was attributed to its oxygen‐rich carbonaceous layered and water molecules are trapped between GO sheets 40,41 . The amorphicity and nano‐crystallinity of synthesized glass and indium tin oxide thin films can be seen in the broad background of about 2θ = 15°‐35° 42 .…”

In contrast, Figure 2B gradually reduced for interlayer spacing from 0.83 to 0.35 nm, where the diffraction pattern is shifted to 26.13 .…”

Assessing hBN Nanoparticles Stability in Trimethylolpropane Triester Based Biolubricants Using Molecular Dynamic Simulation

“…With molecular dynamics simulations, we can predict its stability by interpreting the MSD curve. This method is also adopted to investigate the aggregation of graphene nanoplate in poly-α-olefin lubricating oil , graphene oxide nanosheet dispersion in water 29) and overlapped graphene sheets in linear aliphatic hydrocarbons 30). Referring from both graphs, 0.3, 0.4 and 0.5wt% nanoparticle hBN in suspension are moving very far from the initial position, which indicated by the fluctuated curve.…”

“…This result is indirectly confirmed the previous study conducted by Oztekin et al (2012) that viscosity is proportional to the concentration as well as shear thinning, which means it will increase as the concentration of additives and shear thinning increased. The agglomeration happened is indicated by shear thinning formed 29) Diffusion coefficient or self-diffusion (D) is affected by concentration, temperature, pressure, solvent properties and diffusing chemical properties. In this case diffusion coefficient is a parameter to describe how well the rate of migration of hBN in TMPTO fluid.…”

Ultrastrong Freestanding Graphene Oxide Nanomembranes with Surface-Enhanced Raman Scattering Functionality by Solvent-Assisted Single-Component Layer-by-Layer Assembly

“…Such change indicates that the sp 2 domains in the GO basal plan are bound by the methanol to much greater extent than that deposited from water dispersion. 41 To compare mechanical performance of rGO nanomembranes fabricated in this study 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 low temperature control oxidation of pristine graphite with well-stacked morphology. 42 However, even in this case, the Young's modulus is much lower than that of this study (indicated as a red star in Figure 5e).…”
