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 is the oxidized form of graphene, with O functional groups decorating the sp2 C basal plane.

As a result of presence of the oxygen functional groups, graphene oxide can also be hydrophilic and it can be dispersed in water resolution, opposite to graphene which is hydrophobic. So this property of graphene oxide is very important when mixing the material with ceramic or polymer matrixes when making an attempt to improve their electrical and mechanical properties.

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

Graphene oxide has an especially high surface area; due to this fact, these materials are considered for utilization 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 illness detection, and even for helping in finding cures for cancer and detecting biologically relevant molecules. Graphene oxide has been efficiently used in fluorescent-based biosensors for the detection of DNA and proteins with a promise of higher diagnostics.

Graphene oxide can be used in the biomedical discipline, particularly in drug-delivery systems. Graphene oxide is likely superior to many different anticancer drugs because it doesn't 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 under dry conditions. Uncovered 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 used as containers for corrosive acids. Graphene-coated plastic films might be utilized in medical packaging to improve shelf life.

Graphene oxide mixes readily with many polymers, forming nanocomposites, and vastly enhances the properties of the unique polymer, including 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 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.
