Wu and co-workers proposed a similar strategy, using divinyl benzene (DVB) as micellar cross-linker in a PAAm matrix. The final tough hydrogels reached a fracture toughness of Γ = 26 kJ/m 2 at a much improved water content of 86%. During the tensile test, an admirable stretchability of 10200% was reached without sample failure. In addition, three different stages of deformation were observed during the tensile test, giving rise to three elastic moduli. The tensile behavior in stage I (E = 90 kPa, ε ≤ 8700%) was attributed to the dynamic physical interactions of the hydrophobic DVB aggregates paired with the unfolding and alignment of the PAAm chains. Similar to amorphous poly-mers, in stage II the hydrogel experienced a sudden increase in stress followed by a yield point (the elastic modulus rose to E = 111 kPa, ε ≤ 9400%). In the final stage III, the gel experienced severe strain-hardening with a modulus of E = 357 kPa (ε ≤ 10200%), likely due to a tension shift from the fully aligned PAAm chains onto the cross-linked DVB clusters.
