Description

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
