High Purity >99% Graphene sheet/paper, high mechanical strength and superior electrical conductivity

For applications in sensors, batteries and supercapacitors, thermal control and heat spreading, and EMI shielding.


Graphene sheet, also referred to as graphene paper, is the assembly of individual graphene nanosheets into macroscopic structure to form paper-like material. The achieved freestanding graphene sheet shows a unique combination of outstanding properties such as high mechanical strength, large surface area, and superior electrical conductivity, and stability in electrochemical environment, outperforming many other carbon substrates.

As a functional material, graphene sheet does not only act as a conducting agent, but also as a current collector. This makes graphene sheet, a promising base flexible electrode material for energy storage devices with significantly improved performances in energy density, power density and better life cycle compared to non-flexible conventional electrode architecture.

Electrical Conductivity In Plane 3,700 S/cm

There are two main procedures to prepare free standing graphene sheets, “top-down” and “bottom-up”. The top-down processes attain graphene films from graphite, including vacuum filtration, direct evaporation, and diverse coating techniques. The bottom-up processes are based on the synthesis of graphene films from gaseous carbon sources, such as chemical vapor deposition.

With thermal conductivity and spreading-in-plane conductivity above 550 W/mK, and surface resistivity ranging as low as 0.04 Ω/sq, graphene sheet has following applications but not limited to:

  • Sensors
  • Electrodes for batteries and supercapacitors
  • Thermal control and heat spreading
  • EMI Shielding
