Chemical vapour deposited graphene on Cu foil should be transferred to target dielectric substrate before being used in various applications. This route often involves preparation of a supporting material on graphene before the transfer process and removal of the material after graphene is transferred to a foreign substrate. Herein, we demonstrate a simple process combining graphene transfer and subsequent graphene-based sensor preparation in one route. By applying a thin flexible polyethylene (PE) film onto graphene and subsequently chemical etching Cu foil, this process enables the high-qual...
