Characterizations of rolling–sliding transfer for large‐area graphene onto flexible and transparent EVA plastic. a) A typical Raman spectrum of graphene on EVA plastic. b,c) Colormaps derived from Raman mapping results acquired from the dotted areas in (e). d) Typical UV–vis–NIR spectrum of graphene/EVA film. e) A photograph of clean and large‐area graphene transferred onto EVA plastic and a simple LED circuit in which the transferred graphene acts as a part of wire for the closed circuit.
