Microgel (MG) suspension was prepared using 2-acrylamide-2-methylpropanesulfonic acid (AMPS) and acrylamide (AM) as monomers by in-situ radical polymerization and mechanical crushing, and then the microgel reinforced polyacrylamide (MG-PAM) hydrogel was prepared by triggering polymerization with acrylamide (AM) solution. The structure and morphology of the hydrogel were characterized by FTIR and SEM, and its mechanical properties, swelling properties and energy dissipation properties were measured. The results show that: When the dosage of MG suspension is 40%, the compressive strength of the hydrogel can reach 25.42MPa (95% deformation), the tensile strength and the elongation at break can reach 201.2 KPa and 405.4 % respectively, and the hydrogel has good energy dissipation performance under different strains (70%, 80%). The hydrogel can also withstand different mechanical deformation. It has excellent mechanical properties.
