Overview
CVD graphene on Cu foil monolayer graphene attached to thermal release tape. The graphene can be transferred to a polymer substrate simply by a roll lamination process.

How to Use
- Prepare a roll laminator (or coater) capable of speed control and temperature setting.
- The target substrate and Graphene on TRT are superimposed as shown in the figure and laminated at room temperature.
- After raising the temperature to 100 ~ 110 ° C, laminate [TRT / Graphene / substrate] until TRT loses adhesion (repeat 2-3 times).
Package
We have taken special care to minimize damage on the research surface of graphene. Our graphene film sample packaging is unique such that oxidation affect is minimized and the graphene surface does not come in contact with the inner package surface. As a result, our graphene samples are not damaged nor scratched during the shipping process. We suggest use of tweezers to handle graphene.
Package Process
Precautions
- If the thermal release tape (TRT) is forcibly detached before it loses its adhesion, the graphene may be damaged and not be transferred.
- Adhesive layer may remain as some polymer residue.
- Depending on the substrate, the transfer coverage may vary. (Roughness is important, recommend PET like polymer)
