| titleOfInvention | High-toughness hydrogel preparation method based on high-molecular-initiation crosslinking integrated technology and hydrogel |
| abstract | The invention discloses a high-toughness hydrogel preparation method based on a high-molecular-initiation crosslinking integration technology and a hydrogel. The hydrogel is obtained by homopolymerizing or copolymerizing acrylamide monomers through a free radical aqueous solution, wherein water-soluble macromolecules containing amino groups are used as an initiator and a crosslinking agent, and the macromolecules initiate living polymer chains growing on the crosslinking agent to form branched chains in a disproportionation termination mode and form a physical crosslinking network in an entanglement mode; the macromolecule-initiated crosslinking agent has living polymer chains growing thereon that form a chemically crosslinked network in a coupling-terminated manner, and a certain amount of auxiliary crosslinking agent is added to further increase the chemical crosslinking density, thereby forming a hydrogel having both a physically entangled network of branched chains and a chemically crosslinked network. The high-toughness hydrogel has excellent deformability, high tensile strength, excellent resilience and good temperature resistance, and solves the problem that the existing hydrogel is limited in application due to insufficient toughness. |
