Dry Transfer of CVD Graphene Film Using Adhesion Switchable Ferroelectric Polymers

The transfer of large-area CVD graphene has long remained a limiting step in moving 2D materials from laboratory demonstrations to scalable device manufacturing.

In work now published in Advanced Materials, we demonstrate a fully dry, etchant-free, and automated transfer platform based on adhesion control using switchable ferroelectric polymers (PVDF-TrFE). By engineering interfacial forces through controlled polarization, graphene can be cleanly delaminated from copper and subsequently released onto target substrates without compromising material integrity. The process yields crack-free graphene with >99% coverage, avoids chemical etchants and polymer residues, and operates on minute-level cycle times. This method works equally for MoS2 and BN transfer.
