▎ 摘　　要

NOVELTY - Preparing a degradable polymer involves reacting the polyamine compound with the polyaldehyde compound to obtain a solution containing a Schiff base structure compound in the main chain and mixing solution of the compound with the bifunctional monomer, and catalyzing the reaction through a base catalyst to obtain a product. USE - Method for preparing a degradable polymer for transferring graphene (claimed). ADVANTAGE - The method enables to preparing a degradable polymer, where the solubility is significantly improved, polymer molecules coated on graphene defects and surface impurities will also be degraded and peeled off, thus achieving clean transfer of graphene. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for transferring graphene by using the degradable polymer, which involves generating a graphene layer with a two-dimensional continuous structure on one surface of the metal catalytic substrate, uniformly coating the degradable polymer solution on the surface of the graphene layer away from the metal catalytic substrate, drying to obtain a degradable layer attached to the graphene layer, removing the metal catalytic substrate, and then compounding the target substrate on the surface of the graphene layer away from the degradable layer and decomposing degradable layer in an acidic aqueous solution to obtain the target substrate compounded with the graphene layer.
