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 type of graphene, with O functional teams adorning the sp2 C basal plane.

As a result of presence of the oxygen functional teams, graphene oxide can be hydrophilic and it may be dispersed in water answer, contrary to graphene which is hydrophobic. So this property of graphene oxide is essential when mixing the fabric with ceramic or polymer matrixes when attempting to improve their electrical and mechanical properties.

The size of the graphene oxide flakes can be also tuned and assorted from a few nm to mm. The tunability of both its chemical composition and flakes measurement makes graphene oxide an interesting material in lots of fields: electronics (sensors and clear conductive films), composites supplies, clean energy units, biology and medicine.

Graphene oxide has an especially high surface space; therefore, these supplies are considered for usage as electrode materials 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 material, it may be used for biosensing applications, for early illness detection, and even for aiding find cures for cancer and detecting biologically related molecules. Graphene oxide has been successfully used in fluorescent-based biosensors for the detection of DNA and proteins with a promise of higher diagnostics.

Graphene oxide is also used in the biomedical area, notably in drug-delivery systems. Graphene oxide is likely superior to many different anticancer medicine because it doesn't target healthy cells, only tumors, and has a low toxicity.

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

Graphene oxide mixes readily with many polymers, forming nanocomposites, and enormously enhances the properties of the original polymer, including elastic modulus, tensile energy, electrical conductivity, and thermal stability. In its solid kind, graphene oxide flakes tend to attach to at least one another, forming thin and intensely stable paper-like structures that can be folded, wrinkled, and stretched. Such free-standing graphene oxide films are considered for applications together with hydrogen storage applications, ion conductors, and nanofiltration membranes.
