Abstract
The present disclosure provides a binding agent for graphene film transfer, comprising 5-95 parts by weight of a volatile organic solvent A and 95-5 parts by weight of a volatile organic solvent B. The present disclosure does not use a transition substrate, which greatly reduces the cost, and realizes low-cost transfer. Moreover, the binding agent can be completely volatilized, so that the transferred graphene has no residual glue. The graphene is pure and pollution-free, and a high-quality graphene film can be obtained after the transfer of the graphene. Furthermore, high-quality multi-layer transfer can be achieved and the quality of multi-layer graphene can be guaranteed. Moreover, the graphene can be transferred to any different target substrates. The transfer method provided by the present disclosure has simple operation, good controllability and high repeatability, which can not only realize single-piece transfer, but also can realize roll-to-roll large-area transfer, and can maintain the high quality of graphene after the transfer, so that it is especially suitable for promotion and application of large-scale preparation and production.
