Application

XG Leaf® is a more effective solution than aluminum and copper foils for a wide variety of applications to optimize thermal conductivity, thermal spreading, electrical properties, and corrosion resistance. XG Leaf® is a thin, flexible, and lightweight sheet product built on a foundation of XG Sciences, xGnP® graphene nanoplatelets. By precisely tailoring the composition, density, and our proprietary manufacturing process materials are created with unique properties to optimize thermal and electrical conductivity. Different types of XG Leaf® graphene paper offer outstanding thermal and electrical properties.
  • Thermal conductivity and spreading: in-plane conductivity above 550 W/mK.
  • Electrical properties: formulations are available with surface resistivity ranging as low as 0.04 Ω/sq.
Potential applications include:
  • Heat dissipation.
  • Resistive heating.
  • EMI shielding.
  • Electrodes (thin battery, super capacitor, Li-air etc).
  • Barrier.
  • Layering in composites.
  • Sensors.

Physical properties

  • Thermal conductivity: 550 W/mK (in-plane), 3 W/mK (through plane).
  • Electrical conductivity: 3700 S/cm (in-plane).
  • Electrical resistivity: surface 0.06 Ω/sq, sheet 2.7 μΩ-m.
  • EMI shielding: 53 dB @ 30 MHz, 58 dB @ 1.5 GHz.
