Ultraclean Patterned Transfer of Single-Layer Graphene by Recyclable Pressure Sensitive Adhesive Films
We report an ultraclean, cost-effective,
and easily scalable method of transferring and patterning large-area
graphene using pressure sensitive adhesive films (PSAFs) at room temperature.
This simple transfer is enabled by the difference in wettability and
adhesion energy of graphene with respect to PSAF and a target substrate.
The PSAF-transferred graphene is found to be free from residues and
shows excellent charge carrier mobility as high as ∼17 700
cm<sup>2</sup>/V·s with less doping compared to the graphene
transferred by thermal release tape (TRT) or poly(methyl methacrylate)
(PMMA) as well as good uniformity over large areas. In addition, the
sheet resistance of graphene transferred by recycled PSAF does not
change considerably up to 4 times, which would be advantageous for
more cost-effective and environmentally friendly production of large-area
graphene films for practical applications
