AMG021a CVD Graphene on Copper Foil

ACS Material is an industry-leading graphene on copper foil supplier. ACS Material produces high-quality, high-purity single- and multilayer graphene deposited on 35 μm copper foil via chemical vapor distribution (CVD). Our graphene films are continuous across the surface of the copper sheet on one or both sides. Standard sizes are 2”x2”, 4”x2”, and 6”x4”. Custom sizes are available upon request.

Graphene on Copper Foil (both sides)

Graphene on Copper Foil (Single-sided)

** Note: Copper Foil thickness is now 35μm now and if you need the old thickness of 45μm, please contact us for a quote.

** Standard products have graphene on both sides of the copper foil.

** ACS Material can provide Single-sided CVD Graphene on Copper as shown in the drop-down list. It is prepared by depositing PMMA on the graphene, etch away the graphene on the back side and then remove PMMA. Please note that there might be minor PMMA residues on the graphene surface and you can do a deeper cleaner if necessary. Please contact us if you have any questions or have other special requests.

** ACS Material can also provide large size Monolayer CVD Graphene on Copper (Graphene Factory) made by CVD Method and large size Monolayer CVD Graphene on SiO2/Si by Metal Assisted Exfoliation (MAE Process).

*ACS Material also offers plain quartz substrates in various sizes, please refer to our Quartz Substrate product page for more information. For customization options including CVD graphene transfer services to other size substrates or custom substrates, contact ACS Material today.

AMG021h CVD Graphene on Copper-PMMA Coated

Pretreated graphene is produced by applying PMMA to a copper substrate CVD graphene then removing the "reverse-side graphene". This form of graphene can then be used to study the transfer process by placing it directly in the ammonium persulphate solution to remove the copper followed by immersion in de-ionized water twice for cleaning. This method allows our customers to transfer to different substrates for their needs. A quicker alternative to this method is the ACS Material product Trivial Transfer Graphene?.
