NOVELTY - A surface molecular imprinting polymer material is prepared by: (1) adding graphene oxide to water, carrying out ultrasonic treatment, then adding hydrazine hydrate solution, concentrated aqueous ammonia and fumed silica, carrying out ultrasonic treatment to obtain a dispersion liquid, heating and stirring the dispersion liquid, then washing with clear water for 2-3 times, carrying out suction filtration and vacuum drying to prepare a reduced graphene oxide; and (2) adding 4-nitrophenol, methanol, reduced graphene oxide, methacrylic acid and acrylamide to a reaction vessel, magnetically stirring, then adding ethylene glycol dimethacrylate and azobisisobutyronitrile, filling nitrogen into the reaction vessel, maintaining the temperature for 15-25 minutes, sealing the reaction vessel, reacting in a water bath, subjecting the product to a solvent Soxhlet extraction method to remove p-nitrophenol after the reaction is completed and drying to prepare the product. USE - Surface molecular imprinting polymer material. ADVANTAGE - The surface molecular imprinting polymer material of the reduced graphene oxide can increase the specific surface area and recognition site of the imprinted material. The mass transfer resistance of the template molecule in the adsorption and desorption of the polymer material can be effectively reduced, thus achieving the purpose of shortening the response time and improving the detection sensitivity. DETAILED DESCRIPTION - A surface molecular imprinting polymer material is prepared by: (1) adding 10-20 pts. wt. graphene oxide to 200-400 pts. wt. water, carrying out ultrasonic treatment for 2 hours, then adding 0.1-0.5 pt. wt. hydrazine hydrate solution, 1.5-5 pts. wt. concentrated aqueous ammonia and 1-2 pts. wt. fumed silica, carrying out ultrasonic treatment for 1-2 hours to obtain a dispersion liquid, heating and stirring the dispersion liquid at 95-105 degrees C for 0.5-2 hours, then washing with clear water for 2-3 times, carrying out suction filtration and vacuum drying at 60 degrees C to prepare a reduced graphene oxide; and (2) adding 0.3-0.7 pt. wt. 4-nitrophenol, 35-60 pts. wt. methanol, 90-110 pts. wt. reduced graphene oxide, 1-4 pts. wt. methacrylic acid and 1-4 pts. wt. acrylamide to a reaction vessel, magnetically stirring for 2 hours, then adding 2-5 pts. wt. ethylene glycol dimethacrylate and 25-55 pts. wt. azobisisobutyronitrile, filling nitrogen into the reaction vessel, maintaining the temperature for 15-25 minutes, sealing the reaction vessel, reacting in a water bath at 60-65 degrees C for 28-36 hours, subjecting the product to a solvent Soxhlet extraction method to remove p-nitrophenol after the reaction is completed, and drying to prepare the product.
