As a new type of strategically important material, graphene can be used in many important industries such as scientific research, chip circuit electronics, new energy, new materials, biotechnology, etc., especially for scientific research-grade graphene films, which require extremely stable and high-quality graphite. Graphene, which requires that we can etch away the copper substrate from the common substrate graphene to obtain the graphene/protective layer film, and then transfer the graphene and the protective film to the "suspended substrate". After getting the product, just gently release the product in deionized water to obtain a one-step transfer graphene film that can be directly transferred to various substrates.

In this paper, the one-step transfer of graphene films is based on "bubble-take" graphene. Taking the microcrystalline technology wet transfer method as an example, it introduces the use of ion etchant (such as ammonium persulfate aqueous solution) to dissolve the growth substrate, and then The graphene is transferred from a liquid cleaning solvent (usually deionized water) to the target substrate without drying. Various support layers/substrate layers/protective layers are used to achieve clean and residue-free transfer of graphene. Wet transfer is a one-step process of transferring graphene films based on Microcrystalline Technology's "bubble-taking" graphene. Currently, it is the most common and popular method for transferring graphene films. Graphene films are transferred by themselves. This method has high success rate, stable quality and reliability, and is also an important way to reduce costs and widely promote applications; this method can also minimize operating procedures and quantities, reduce residues and damage to the transferred graphene film .
