Graphene Studies Using Raman Spectroscopy

It is the basic structural element of some carbon allotropes including graphite, carbon nanotubes and fullerenes. Distinguishing the number of graphene layers as well as quantifying the impact of disorder on its properties is critical for the study of graphene-based devices.

Graphene

Graphene (/ ˈ ɡ r f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. The name is a portmanteau of graphite and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.

FUNCTIONALIZED GRAPHENE

Moreover, adsorption isotherms, kinetics and thermodynamic data of different functionalized graphene-based materials towards a wide range of organic pollutants were analyzed and tabulated. In each evaluation topic, environmental and human health protection is subject for discussion, as well as the scientific breakthrough works available in high impact journals in the field.

Graphene

Graphene sheets-one-atom-thick two-dimensional layers of spSUP2/SUP-bonded carbon-are predicted to have a range of unusual properties. Their thermal conductivity and mechanical stiffness may rival the remarkable in-plane values for graphite (~3,000WmSUP-1/SUPKSUP-1/SUP and 1,060GPa, respectively); their fracture strength should be comparable to that of carbon nanotubes for

Superhydrophobic graphene

2020/12/5Hence the characterization of these graphene based materials is very important in terms of surface modification, roughness and water contact angle measurements. Wang et al. [ 74 ] modified graphene oxide using pPDA for making it more superhydrophobic in nature by surface polymerization and thus it got self-assembled over the surface of GO.

Graphene

In this context, the use of graphene based materials like graphene oxide (GO) and reduced graphene oxide (RGO) are smart alternative choices. GO is synthesized from low cost and available graphite. It contains large number of oxygen containing functional groups like hydroxyl, carbonyl, carboxyl and epoxy which make it compatible with most of the organic polymers.
