- Graphite oxide, formerly called graphitic oxide or graphitic acid, is a compound of carbon, oxygen, and hydrogen in variable ratios, obtained by treating graphite with strong oxidizers.
- Graphene The maximally oxidized bulk product is a yellow solid with C:O ratio between 2.1 and 2.9, that retains the layer structure of graphite but with a much larger and irregular spacing
- Graphene The bulk material disperses in basic solutions to yield monomolecular sheets, known as graphene oxide by analogy to graphene, the single-layer form of graphite
- Graphene oxide sheets have been used to prepare strong paper-like materials, membranes, thin films, and composite materials.
- Initially graphene oxide attracted substantial interest as a possible intermediate for the manufacture of graphene
- The graphene obtained by reduction of graphene oxide still has many chemical and structural defects which is a problem for some applications but an advantage for some others

Carbon nanotubes (CNTs) have attracted enormous attention in recent years due to its unique physical, electronic, optical and potential applications in materials science and nanotechnology. The van der Waals interaction between tubes, however, makes CNTs aggregate in most organic solvents and aqueous solutions, which is the major limitation of their practical applications.Various approaches have been studied to alter the CNT surface to promote the dispersion of individual nanotubes and prevent their reaggregation. On the basis of this widely accepted viewpoint, numerous techniques such as covalent bonding, surfactant coating and polymer wrapping have been developed for surface modification or sidewall functionalization.These methods, however, are complicated, time-consuming and cause permanent damage to the CNT structure and properties of the surface, which produces residues of the dispersion agent for the final product.
