3D Graphene Foam

Graphene is known as a 2D material, while it can be grown into 3D structures via CVD (chemical vapor deposition) processing graphene onto the surface of metal foams. The metal skeleton is then etched away and left a visible, porous 3D graphene foam structure.

The 3D graphene foam can well preserve the properties of 2D graphene of being highly conductive, surface abundant, and mechanically robust, together with unique 2D electronic behaviors. Additionally, the porosity and large curvature offer new functionalities, such as rapid mass transport, ample open space, mechanical flexibility, and tunable electric/thermal conductivity. Particularly, the 3D curvature provides a new degree of freedom for tailoring the catalysis and transport properties of graphene. The 3D graphene with those extraordinary properties has shown great promises for a wide range of applications, especially for energy conversion and storage.

Special Properties

• Electrical Conductivity—Its porous structure provides both low electrical and low fluid flow resistance. Large current distribution areas are possible due to the enormous amount of surface area of the foam.
• Corrosion Resistance—3D graphene foam is inert to a wide range of very reactive acids, bases, and organic solvents. At high temperatures it will form carbides, while it is inert to non-carbide forming metals.

Applications

Currently, the two focus areas of 3D graphene foam have been around sensors and energy storage devices. Typical applications are as follows:

• Sensors

3D graphene foam has the characteristics of large electrochemically active surface area, high electrical conductivity, and pure graphene surface to provide high sensitivity, and it can be used in numerous sensors:
