▎ 摘 要
NOVELTY - Transferring graphene involves immersing the metal catalyst and the graphene sequentially deposited on the substrate in a polar solvent and then separating the immersed metal catalyst and graphene from the substrate in the polar solvent. The separated metal catalyst and graphene is then immersed in a low polarity solvent, while changing the top and bottom of the graphene and the metal catalyst in the low polarity solvent. The graphene is binded to a desired substrate and the metal catalyst is removed. USE - Method for transferring graphene used in organic electroluminescent device and field-effect transistor (claimed).
