Enerage develops foam sponge with well-dispersed graphene. The sponge can be applied as a separator for water and oil due to the lipophilicity of graphene. Unlike the conventional sponge, graphene foam sponge will adsorb oil, separate oil, and filtrate the solid residue in oil in order to achieve reusable water and oil. Additionally, the sponge can be used as anti-static and anti-collision materials in packing.
