3D-Graphene sheet is a flat sheet, 100-300 μm thick, that can be utilized as-is or in conjunction with 3D-Paints.
This research grade (not for human use) 3D-Graphene sheet can be utilized as-is or in conjunction with 3D-Paints. Provided as flat sheets 100-300 μm thick, 3D-Graphene sheets are flexible, rollable, and foldable. They may also be cut and punched as desired to achievable the necessary dimensions for a given application. 3D-Graphene sheets may also be used as 3D-printing substrates in conjunction with other 3D-Paints. 3D-Paints 3D-printed or otherwise extruded directly onto the 3D-Graphene sheet will chemically fuse with the material. This feature permits the user to 3D-print or otherwise impart patterns directly onto the flexible substrate using materials from the 3D- Paint family. 3D-Graphene sheets are comprised of approximately 75 wt.% graphene powder (5-20 μm lateral flake dimension) bound by a network of 25 wt.% polylactide-co-glycolide (PLG). 3D-Graphene sheets exhibit an electrical conductivity of approximately 500 S/m, which can be further increased to approximately 600 S/m with brief thermal annealing at 50 °C.
After being 3D-printed onto, 3D-Graphene sheets and the resulting composite structures should be washed in 70% ethanol or 70% isopropyl alcohol followed by water, to remove residual solvents, prior to use. It can be utilized in this form, as a flexible, bioactive, electrically conductive biomaterial. 3D- Graphene has numerous electrogenic tissue (nerve, muscle, cardiac) repair and regeneration applications as well as flexible bioelectronic and wearables applications. 3D-printed 3D-Graphene can serve as an effective cell scaffold for in vitro or in vivo use.
