                Graphene Foam Put to Use

                Graphene is known as a ‘wonder material’, thanks to its ultra-lightweight, 2D status. Its unique properties can be applied to foam, making it useful for a range of applications. In this post, we take a look at Graphene foam put to use!

                How is Graphene foam made?

                Graphene foam is a solid, open-cell foam, which is made up of single-layered sheets of Graphene. The foam is usually made by growing Graphene via a Chemical Vapour Deposition (CVD) process on a 3D metal foam structure, then removing the metal to leave behind the 3D Graphene foam.

                What makes it different?

                As a material, Graphene is super thin and lightweight, yet very strong. These special properties are translated to the foam, making it perfect for use in research and development.

                The molecular design of Graphene-based materials also has a positive environmental and economic impact. The design has appealing features such as a low cost, eco-friendliness, flexibility and versatility.

                Graphene foam in real applications

                Graphene foam can be a foundation for energy storage or flexible sensing applications. It can also allow photosensitiser polymers to experience chemical change, which is a unique property for a metal foam.

                When researchers at the University of Catania in Italy were developing a freestanding apparatus for use in a photocatalysis application, they opted for a 3D Graphene hybrid material, which in this case was Graphene foam. They created this hybrid material by CVD of Graphene-on-Nickel foam and combined it with the organic compound Polyporphyrin. Nickel foam that was provided by Goodfellow acted as the scaffold template for this creation. Promotion of direct and extensive contact of the Graphene and the Polymers were critical for success, and so the foam structure of Graphene-on-Nickel provided them with the extensive Graphene surface area that was required in order to succeed.

                A graphene foam can be also used in sensors, purification or absorption filter materials, as a catalytic support or electrodes material for energy storage applications etc.
