Properties And Applications Of Graphene Oxide

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

Due to the presence of the oxygen functional groups, graphene oxide is also hydrophilic and it can be dispersed in water resolution, contrary to graphene which is hydrophobic. So this property of graphene oxide is essential when mixing the fabric with ceramic or polymer matrixes when making an attempt to improve their electrical and mechanical properties.

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

Graphene oxide has a particularly high surface space; due to this fact, these materials 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 materials, it may be used for biosensing applications, for early illness detection, and even for helping find cures for cancer and detecting biologically relevant molecules. Graphene oxide has been efficiently utilized in fluorescent-based mostly biosensors for the detection of DNA and proteins with a promise of better diagnostics.

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

In coating technology graphene oxide can be used also. Multilayer graphene oxide films are optically clear and impermeable underneath dry conditions. Exposed to water (or water vapor), they permit 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 could be used in medical packaging to improve shelf life.

Graphene oxide mixes readily with many polymers, forming nanocomposites, and greatly enhances the properties of the original polymer, together with elastic modulus, tensile power, electrical conductivity, and thermal stability. In its strong kind, graphene oxide flakes have a tendency to connect to one another, forming thin and extremely stable paper-like structures 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.
