▎ 摘　　要

NOVELTY - Preparation of polymer porous hydrogel comprises uniformly dispersing graphene oxide (GO) in solvent; adding to lipophilic modifier, reacting, centrifugally washing, vacuum drying; uniformly dispersing in water, adding monomer, crosslinking agent, and initiator, adding water; adding pore-forming agent, homogenizing or ultrasonically processing, transferring into hydrothermal reaction kettle, reacting, removing pore-forming agent and unreacted product, and drying. The pore-forming agent is 6-20C alkane and/or cycloalkane. USE - Method for preparing polymer porous hydrogel (claimed). ADVANTAGE - The product has simple preparation, low cost, controllable hole diameter, good permeability, and good swelling performance and adsorption performance. DETAILED DESCRIPTION - Preparation of polymer porous hydrogel comprises uniformly dispersing graphene oxide (GO) in solvent into 0.05-1% GO sol, where GO is 50-2000 nm; adding GO sol to 0.5-300% lipophilic modifier, reacting for 0.5-24 hours while stirring at room temperature, centrifugally washing, vacuum drying to obtain modified GO; uniformly dispersing in 50-500 times water at 40-65 degrees C, adding 20-600 times monomer, 1-75 times crosslinking agent, and 1-20 times initiator, adding water to a content of 0.08-1%; adding 2-8 times pore-forming agent, homogenizing or ultrasonically processing for 5-60 minutes to form oil-in-water high internal phase emulsion, transferring into hydrothermal reaction kettle, reacting for 12-48 hours at 55-80 degrees C, removing pore-forming agent and unreacted product, and drying at 40-65 degrees C for 24-48 hours. The pore-forming agent is 6-20C alkane and/or cycloalkane.
