Transfer of two-dimensional (2D) materials such as graphene and MoS2 is essential for device integration, but existing methods introduce contamination or mechanical damage. Conventional wet transfer, using a PMMA support layer and KOH etching, leaves polymer and etchant residues, wrinkles and bubbles, while PDMS-based dry stamping avoids liquids but often tears flakes and deposits adhesive residues. Here we demonstrate a simple, etch-free and acetone-free semi-dry transfer using a hydrophilic polymer layer. This method preserves folds in few-layer MoS2 and enables device transfer onto PVC, a solvent-sensitive polymer that cannot withstand PMMA- or acetone-based processes, yielding clean, intact 2D films on both rigid and flexible substrates.
