Overview | Product Information | Related Products

Graphene sheet (CAS number 7782-42-5), 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, 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.

More on Graphene Sheets

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
