3D Graphene Foam — Supercapacitor & EMI Shielding Research
Free-standing 3D graphene foam synthesized by CVD on a nickel template (nickel subsequently etched away). The result is a lightweight, highly conductive, flexible graphene network with specific surface area ~850 m²/g — ideal for supercapacitor electrodes, EMI shielding composites, strain sensors, and thermal interface materials.
Key Specifications
- Electrical conductivity: ~10³ S/m
- BET surface area: 700 – 1000 m²/g
- Thickness: 0.5 mm – 5 mm
- Density: ~5 mg/cm³ (ultra-lightweight)
- Flexibility: Highly flexible, can be compressed and recover
Applications
- Supercapacitor and pseudocapacitor electrodes
- EMI shielding composites
- Piezoresistive strain sensors
- Thermal interface material
- Flexible electronics substrate
