FULL DESCRIPTION

It is made from oxidizing the thinnest layer of graphite. Graphite consists of millions of ultra-thin layers of graphene. A strong oxidizing agent is used to convert graphite into graphite oxide. Because of that, the graphite material expands significantly. This results, in turn, helps to separate the individual layers. Further, graphite oxide is exfoliated in water using an advanced sonication process. It helps to produce single or fewer layers-thick graphene, which is known as graphene-oxide. The material developed through this intensive process provides a layer of graphene. This layer is 2 dimensional and only 1 atom-thick. The graphene-oxide is comparatively thinner than conventional graphite or graphite oxide material. The functionalization like epoxide, carbonyl, carboxyl and hydroxyl groups is needed to change the properties of graphene-oxide to use in the various applications. It is commercially available in a nano-powder and dispersed form. It can also utilize as a film on a substrate. Generally, it readily dispersed in water and other organic solvents due to the strong attached oxygen group. It is also soluble in a polymer matrix and fluorescent in nature.
It is used in the production of the transparent conductive film, flexible electronics, and biosensors. It is also used to make pure Graphene by the active chemical reduction. This method is one of the cheapest and most efficient processes. It is partially reduced to form reduced graphene-oxide (rGO), where most of the oxygen group has removed. There are numerous promising applications of commercial and research grade graphene-oxide. It is used extensively in R&D laboratories, as well as in various industries, due to its immensely useful properties.
The graphene-oxide is an electrically non-conductive due to its disruptive SP2 bonding network; Whereas it can transform into conductive by reducing and restoring “π”-network. Commercial graphene-oxide, structurally, has 3 strong electron bonds and 1 loose bond with a weak connection. These together form a collective electron pool.

USES AND APPLICATIONS

There are numerous promising applications for commercial graphene-oxide. It is used extensively in research and development (R&D). It finds diverse usage in various industries, due to its immensely useful properties.

These are the numerous ways in which commercial graphene-oxide finds application in:

Electronics – Due to its immensely thin structure and higher electrical conductivity it is increasingly used to replace traditional silicon components in conventional electronic devices.

Heat-Resistance – The material can withstand extreme temperatures effectively. It is being used in numerous heat-resistant applications, in R&D, and in the defense industries too.

Optical applications – Due to its higher optical transparency, the material is rapidly replacing ITO (Indium Tin Oxide) as the choice of materials for electronic displays, such as LEDs, and biosensors. This material is also being seen increasingly in computers, tablets, and smartphones.

Energy storage – The higher electrical and heat conductivity is also making commercial graphene-oxide a top choice for use in batteries and super-capacitors as it allows faster charging and restores more energy as compared to conventional materials used in cells.

Apart from these, there are numerous other applications for graphene-oxide for research and commercial use.
