Properties And Applications Of Graphene Oxide

Graphene Oxide Powder (2-5 Layer, Dia:7,5 um, SA: 420 m2/gr) is a two dimensional material. It is the oxidized form of graphene, with O functional teams adorning the sp2 C basal plane.

Because of the presence of the oxygen functional groups, graphene oxide can also be hydrophilic and it can be dispersed in water solution, contrary to graphene which is hydrophobic. So this property of graphene oxide is very important when mixing the material with ceramic or polymer matrixes when trying to improve their electrical and mechanical properties.

The size of the graphene oxide flakes will be also tuned and varied from a few nm to mm. The tunability of each its chemical composition and flakes size makes graphene oxide an appealing material in many fields: electronics (sensors and clear conductive films), composites materials, clean energy gadgets, biology and medicine.

Graphene oxide has an especially high surface area; subsequently, these materials are considered for usage as electrode supplies in batteries and double-layered capacitors, as well as fuel cells and solar cells.

Graphene oxide can be utilized as biosensors. Since graphene oxide is a fluorescent materials, it can be used for biosensing applications, for early disease detection, and even for aiding in finding cures for cancer and detecting biologically related molecules. Graphene oxide has been successfully utilized in fluorescent-based mostly biosensors for the detection of DNA and proteins with a promise of higher diagnostics.

Graphene oxide can also be used within the biomedical field, notably in drug-delivery systems. Graphene oxide is likely superior to many other anticancer medicine because it does not target healthy cells, only tumors, and has a low toxicity.

In coating technology graphene oxide can be utilized also. Multilayer graphene oxide films are optically transparent and impermeable below dry conditions. Uncovered to water (or water vapor), they permit passage of molecules smaller than a sure size. Glassware or copperplates covered with such a graphene "paint" can be used as containers for corrosive acids. Graphene-coated plastic films could be utilized in medical packaging to improve shelf life.

Graphene oxide mixes readily with many polymers, forming nanocomposites, and significantly enhances the properties of the original polymer, including elastic modulus, tensile power, electrical conductivity, and thermal stability. In its solid type, graphene oxide flakes tend to attach to 1 one other, forming thin and extremely stable paper-like buildings that may be folded, wrinkled, and stretched. Such free-standing graphene oxide films are considered for applications including hydrogen storage applications, ion conductors, and nanofiltration membranes.
