Graphene Oxide (GO) is a formulation of graphite being treated with oxidizers. The chemical bondage of carbon, oxygen, and hydrogen in ratios results in a yellowish solid bulk product with a C:O ratio between 2.1 and 2.9. Graphite is an allotrope of carbon and occurs naturally. It has stacked up layers of honeycomb lattice-shaped structure with a two-dimensional arrangement of graphene. It can be further processed to change or enhance some features to make it more efficient to use. Reduced GO (RGO), Chemically Modified Graphene (CMG), or Chemically Converted Graphene (CCG) are types that are derived from it.

At Shilpa Enterprises, we produce graphene oxide by the Modified Hummers Method. Alternatively, we sometimes use the chemical vapor deposition method, as it is convenient. Graphene oxide contains 77% carbon and 22% oxygen, whereas 1% other elements. The GO has a Carbon Purity of approximately 99% and a bulk density of 0.48g/cc. Our product has an excellent aspect ratio where the length of the product reaches 5 to 10μm. It is black in color with 1 to 3 layers having a thickness of about 2 to 4 nanometers. It has a very high electro-sorption capacity.

We sell regular as well as customized pack sizes of Graphene oxide powder. It is also available in disperse form. Researchers can also find relatable and helpful functional groups of graphene oxide at a low-cost, exhibiting the best quality possible.

Properties of Graphene Oxide

• Dispersion In Water – Graphene oxide contains oxygen and hydrogen; it disperses quickly in water and organic solvents. When this material combines with polymers or ceramics, it increases the electrical and mechanical properties of it.

• Insulation – Due to the sp2 bonding networks, it acts as an insulator in matters of electrical conductivity.

• Hygroscopicity – The functional groups (hydroxyl, epoxy, and carboxyl groups) of Graphene oxide are very hydrophilic. They absorb water in the gaps between the layers.

• Reactivity – The GO is highly reactive with various chemicals, significantly reducing reagents.

• Stress Tolerance – It is one of the most rigid materials on earth. Graphene has toughness six times more than that of a diamond, and yet it is light in weight than steel.

• Thermal Conductivity – The GO acts as a heat insulator where it can withstand 5300 W⋅m−1⋅K−1.

• Toxicity – It behaves toxically on many bacteria resulting in having anti-bacterial properties.
