| Application |
- One of the likely applications of Graphene Foam is in chemical sensing. Graphene sensors which have been made with Graphene Foam were found to be about ten-times more sensitive than ones currently on the market, detecting 20 parts-per-million of nitrogen dioxide. Further, the graphene sensors were able to detect gases at room temperature, while many commercial sensors today require high temperatures to work properly. The porous graphene is not only more effective than current commercial sensors it also can easily be reused. In order to "empty" the graphene of trapped gas molecules, all the graphene needs is an electric shock. Graphene Foam graphene may also be used in energy storage, such as supercapacitors and batteries. The structure of the graphene foam opens the potential to store massive amounts of energy for example, hydrogen. The Graphene Foam has a high surface area thanks to its porous nature, giving it a high electrochemical capacitance.
- The electrical and structural properties of CVD grown Graphene Foam are superior when compared to the properties of its rivals, chemically derived reduced graphene oxide and few-layered graphene nanoplatelets.
