We report a large-area, dual-scale metal transfer method by using a difference in adhesive force. Rigiflex polyurethane acrylate (PUA) molds with engraved nanoscale patterns were used to transfer metal layers (Au or Al) to flexible polyethylene terephthalate (PET) substrate. Transfer process was performed sequentially for the metal layers on ridge and valley regions of the mold, resulting in a dual-scale metal transfer from a single master. A simple metal wire grid polarizer was fabricated and analyzed using this method.
