Substrate
Substrates are customer provided and can vary widely. The specific graphene adhesion characteristics cannot be known for all customer substrates; as such, graphene transfer onto custom substrates is conducted on a best-effort basis and results may vary. Please contact us to discuss the properties of the substrate in question.
