CNT/Graphene Dispersion

The unique properties of graphene, a one-atom-thick layer of connected carbon atoms with a two-dimensional honeycomb lattice, has attracted increasing attention for a wide range of applications varying from electronic devices, to composites, and biological applications. Several approaches have been developed for the synthesis of graphene dispersion in the organic solvent.

Graphene dispersion has rapidly become an amazing form of carbon that may be used as active components in a wide range of applications such as field-effects transistors, transparent conductors, liquid crystal displays, electromechanical resonators, composites, energy storage, and photovoltaic devices. To accelerate the use of graphene dispersion and tailor its properties, homogeneous colloidal suspensions of individual graphene sheets are always expected, for various processing of the graphene materials such as films and paper depositions, modifications and functionalization chemistry of the edges, and defects of graphene sheets are preferred to be conducted in the liquid phase.

Graphite dispersion is a layered material that can be readily exfoliated in the organic solvent to yield stable graphene dispersions consisting mostly of single-layer sheets, which are referred to as graphene dispersion. This provides a very convenient setting for the implementation of solution-phase techniques toward the conversion of graphene to graphene dispersion by way of chemical reduction which can be used in films and paper-like materials.

Graphene dispersion organic solvent: Exfoliated graphene oxide (GO) is the ideal alternative for the production of solution-processable graphene, as it can be synthesized in large quantities from inexpensive graphite powder and can readily yield stable dispersions in various solvents. GO is an oxidized graphene sheet having its basal planes decorated mostly with epoxide and hydroxyl groups, in addition to carbonyl and carboxyl groups located at the edges.

Graphene dispersion is the ‘‘thinnest’’ known material, and it exhibits extraordinary electronic, chemical, mechanical, thermal and optical properties that have made it a critical material in the 21st Century. Graphene dispersion holds a great promise for use in energy storage materials, drug delivery systems, biosensors, polymer composites, liquid crystal devices, super-capacitors, nanoelectronics, and others.
