3D Graphene Foam
Our 3D graphene foam is an interconnected arrangement of graphene sheets which together form a highly porous three-dimensional network. The 3D foam is comprised solely of graphene, and we can embed within select matrix materials upon request.

Template-Assisted CVD Growth
Our 3D graphene foam materials are grown via a template-assisted CVD process utilizing nickel foam as the growth substrate. Due to carbon’s high solubility in nickel, the carbon is initially adsorbed into the nickel surface. However, as the material cools, the carbon precipitates out onto the nickel surface to form an outer carbon shell of few-layered graphene. At this stage, the obtained structure is composed of both carbon and nickel.

Utilizing scalable CVD technologies and manufacturing processes, we offer state-of-the-art 3D graphene foam materials in mass volumes and at affordable price points.
Making Freestanding 3D Graphene Foam
To obtain freestanding 3D graphene foam, our team follows a thorough etching and rinsing protocol. The etching protocol is performed to remove the nickel content from the graphene-coated nickel foam structure, following which a rinsing protocol is carried out to leave behind a 3D foam comprised solely of graphene.
