Evaluation of the dispersion properties of graphene oxide/cetyltrimethylammonium bromide for application in nanocomposite materials

Abstract

The properties of thermal diffusivity and Z potential of the GONPs/CTAB nanofluid were studied as a function of GO concentration (in the range between 4 and 12% w/v), temperature (35 and 50 °C) and time (30 and 60 min) under ultrasound.

Significant Increase in the Dipole Moment of Graphene on Functionalization: DFT Calculations and Molecular Dynamics Simulations

“…These interactions arise from the overlapping π orbitals of carbon atoms in the hexagonal lattice structure of graphene. When multiple graphene layers stack together, these π orbitals align and form π–π bonds, which contribute to the structural stability of graphene but also pose challenges to its solubility in various solvents . Therefore, graphene oxide (GO) frequently comes into existence as it overcomes the limitations of graphene.…”

“…When multiple graphene layers stack together, these π orbitals align and form π–π bonds, which contribute to the structural stability of graphene but also pose challenges to its solubility in various solvents. 4 Therefore, graphene oxide (GO) frequently comes into existence as it overcomes the limitations of graphene. The hydrophilic nature and water dispersibility of GO are due to the presence of polar functional groups and it important for facilitating the processing and chemical modification of GO.…”
