CVD Graphene Films with PMMA Coating

The CVD graphene films consist of monolayer graphene grown on copper foil substrates. Monolayer graphene is a one-atom-thick sheet of carbon with a honeycomb crystal lattice structure, measuring 0.34 nm in thickness. As part of the unique family of two-dimensional materials, graphene exhibits exceptional electrical and thermal properties along with selective permeability, making it suitable for a wide range of applications.

The PMMA coating enhances CVD graphene films by providing a temporary protective polymer layer that simplifies transfer to various substrates. This thin and uniform coating stabilizes the delicate graphene structure during handling and can be easily removed after transfer, ensuring high-quality integration with minimal defects.

The company offers PMMA-coated monolayer graphene on copper foil in three standard formats, with the capability to support roll-to-roll growth. It also provides expertise in transferring CVD graphene onto polymers, silicon wafers, and other custom substrates.

It is also possible for the company to produce stacked bilayer and trilayer graphene on copper through a wet transfer process, available in 5 x 5 cm and 8 x 8 cm sheet sizes.
