Chemical vapor deposited large-area graphene transfer process to different flexible substrates is one of the most critical aspect to explore a wide range of reliable applications. In this prospect, transfer of graphene on emerging cellulose based flexible paper and other lightweight substrates for various applications is of great importance. Here, we developed a simple and effective approach of polymer-free graphene transfer process onto a moldable flexible substrate. The synthesized graphene on Cu foil was hot pressed and attached to the substrate depending on the moldable temperature without any structural deformation. Etching the base Cu foil, a clean coating of graphene was obtained on the cellulose acetate (CA) based substrate. The successful coating of conducting graphene film was confirmed by optical, scanning electron microscope (SEM), Raman, atomic force microscope (AFM) and current (I)-voltage (V) studies. The developed process can be significant for graphene transfer on various moldable substrate materials. (C) 2015 Elsevier B.V. All rights reserved.
