NOVELTY - Preparing polymer modified graphene sponge, comprises preparing aqueous graphene oxide solution, adding alkali solution to adjust pH to 9-10, then adding polyamine polymer, ultrasonically dispersing, transferring into a hydrothermal reaction kettle, reacting at 100-200 degrees C for 8-48 hours, washing the obtained product with water to neutralize, lyophilizing for 2-5 days, and calcining at 200-300 degrees C for 2-5 hours to obtain final product. USE - The method is useful for preparing polymer modified graphene sponge. ADVANTAGE - The sponge has luxuriant pore structure, high compression performance and recovery performance.
