Abstract: The invention provides an active/controllable graphene oxide surface ion imprinted polymer, and a preparation method and application thereof, belonging to the technical field of preparation and separation of materials, wherein the graphene oxide surface ion imprinted polymer is prepared from a coupling agent, a functional monomer, a cross-linking agent and an initiator by using graphene oxide as a substrate and metal ions as a template in a reversible addition-fragmentation chain transfer polymerization manner. The problems to be solved in the invention are as follows: the thickness of a surface polymer layer is uncontrollable; template molecules cannot be thoroughly eluted because of being embedded deeply; and the adsorption rate is low, etc; the graphene oxide surface ion imprinted polymer is mainly used for adsorbing corresponding metal ions in aqueous solution and has good absorption effect at room temperature and obvious selective separation effect; and the graphene oxide surface ion imprinted polymer can be reused frequently.
