How do you make graphene oxide paper?

Preparation. The starting material is water-dispersed graphene oxide flakes. The aqueous dispersion is vacuum filtrated to produce free standing foils. The thickness of these foils is typically in the range of 0.1-50 micrometers.

What is graphene paper used for?

Lightweight and flexible, yet durable, graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice. The material has been used to better solar panel technology, to enhance medical devices, and for the overall benefit of chemical and industrial processes.

What is the difference between graphite and graphene oxide?

While graphite is a 3 dimensional carbon based material made up of millions of layers of graphene, graphite oxide is a little different. While graphite oxide is a multilayer system in a graphene oxide dispersion a few layers flakes and monolayer flakes can be found.

Is graphite oxide the same as graphene oxide?

Graphite oxide and graphene oxide are very similar , chemically, but structurally, they are very different. The main difference between graphite oxide and graphene oxide is the interplanar spacing between the individual atomic layers of the compounds, caused by water intercalation.

How is graphene extracted from graphite?

The top-down technique for graphene production uses physical exfoliation to procure graphene from graphite. Graphite contains millions of layers of graphene that stacked atop one another. The top-down method for graphene production allows you to separate individual layers of graphene from its graphite form carefully.

What is graphene oxide powder?

Graphene Oxide is an allotrope of carbon that has a hexagonal symmetry and is considered to have a 2D structure. It has a layered pattern that allows it to have a high tensile strength and conductivity. It is available in a variety of forms such as pastes, sheets, powders and dispersed solutions. 900704.
