Development and performance evaluation of macropore intelligent plugging hydrogels.

This rapidly boosts crosslinking density and network entanglement, resulting in a remarkable viscosity increment.At a mass ratio above 1.5:1, the crosslinking points of ACL-HG’s chemical crosslinked network are saturated, and the low proportion of GQDs-Gel significantly weakens the pore-filling effect of physical crosslinking on the double network, resulting in a decreasing trend of system viscosity.The double network system takes over 14 days to attain final gelation, with no notable changes in the gel thereafter.Hence, the mass ratio of 1.5:1 is selected as the optimal experimental formulation for subsequent performance assessments.
