摘要
Disclosed is a graphene electrochemical transfer method assisted by multiple supporting films, comprising: (1) growing graphene on a substrate, and then spin-coating a thin layer of photoresist on a surface of the graphene as a first film; (2) spin-coating n layers of thick, tough, and selectively dissolvable polymer films on the surface of the first film as an top film; (3) dissociating the multi-layer composite film and the graphene from the surface of the substrate by an electrochemical process, and dissolving the thick polymer films which is the top film with a first solvent; (4) after cleaning, transferring the thin first film and the graphene to a target substrate, and finally dissolving the thin first film away with a second solvent to complete the transfer process. This transfer process is fast, stable, and capable of transferring a large-size graphene, which may promote the large-scale application of graphene.
