▎ 摘  要

NOVELTY - The method involves placing a viscous agent on the graphene side of the growth substrate/graphene and heat it to melt, and cooling at room temperature to obtain a growth substrate/graphene/viscosity agent composite structure. The growth substrate in the growth substrate/graphene/adhesive/supporting skeleton composite structure is removed to obtain the graphene/viscosity/supporting skeleton composite structure using the chemical etching method. One side of the graphene/viscosity/supporting skeleton composite structure is attached to the target substrate. The supporting skeleton is removed after the primary drying. The secondary drying is performed to obtain the target substrate/graphene/viscosity agent composite structure. The adhesive in the target substrate/graphene/adhesive composite structure is cleaned and removed to obtain a target substrate/graphene combination using an organic solvent, and is cleaned and dried to complete the transfer. USE - Auxiliary transfer graphene method for supporting skeleton/adhesive composite structure used in manufacturing of electronic device and photonic device. Can also be used in scientific and industrial sectors, and to research and expand large-scale industrial production. ADVANTAGE - The supporting frame/denaturant composite structure auxiliary transfer graphene method: utilizes the composite structure of the supporting framework combined with the adhesive agent as the intermediate layer, thus providing enough mechanical strength; avoids cracking when large area is transferred; and realizes the high mechanical performance when transferring the intermediate layers. The method is easy to operate, easy to remove and pollution-free, and it can realize industrial large-scale production. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic flow diagram of transferring graphene. (Drawing includes non-English language text).
