Trivial Transfer Graphene (WJSSA/F) is obtained by etching away the copper substrate, which is based on CVD Graphene on Copper, Pretreated with PMMA.The graphene/protective layer film is then transferred to the prepared "overhanging substrate".Receiving the product,customer can simply release it gently in deionized water to obtain.The Graphene that can be directly transferred to any substrate.
