  • Patent number: 11932717
    Abstract: Disclosed are a green synthesis method of an antibacterial super-porous hydrogel, a product of the antibacterial super-porous hydrogel and an application of the antibacterial super-porous hydrogel to degradation of various pollutants in wastewater treatment. The super-porous hydrogel based on poly (ionic liquid) is prepared by copolymerization of an imidazole type ionic liquid with double bonds and polyethylene glycol diacrylate (PEGDA) as a cross-linker. In the reaction system, water is a good solvent for the monomer ionic liquid and PEGDA, but a poor solvent for the poly (ionic liquid); when an initial concentration of the ionic liquid is higher than 25%, the phase separation typically proceeds through poly(ionic liquid) formation, interconnected networks with macroporous structure could be obtained by photo-crosslinking.
