ITME will provide readily available graphene on flat copper substrates to enable biofunctionalization and will contribute to the required patterning activities and carry out graphene transfer on optical fibres.
A sheet of copper foil is inserted into the reactor chamber where graphene is grown in a chemical vapour deposition process.
Within a few hours a single layer of carbon atoms will cover the entire surface of the foil.
Graphene is recovered from the surface of the copper foil in a process named electrochemical delamination.
When inserted into a simple electrolyte and polarised against a reference electrode, the copper foil will produce hydrogen bubbles that gently detach graphene from its surface.
Delaminated graphene is floating on the electrolyte surface.
The process of electrochemical delamination is optimised to guarantee uniform and high-quality graphene layers for photonic applications.
