“…In addition, research has pointed out that without the addition of SA into polyethylene glycol (PEG) (meth), acrylate hydrogel for specific mechanical properties showed a poor state, from 0% to 2% when the content of the SA was added, and hydrogel compression modulus, strength, failure strain, and toughness had an apparent rising trend. Thus, the SA network to join, combined with the covalent network of PEG (meth) acrylate, the performance of the hydrogel improved to a certain extent [ 39 ].…”

“…3h and i). 37–46 It was found that the bicontinuous hydrogel achieved the optimal elastic modulus of ∼92 MPa and fracture strength of ∼10.3 MPa, along with a remarkable toughness of ∼14.7 MJ m −3 , outperforming most existing tough hydrogels and biological tissues.…”

“…A comparison of our bicontinuous hydrogel with the reported tough hydrogels and cartilage in terms of (h) fracture strength and (i) toughness in relation to Young's modulus. [37][38][39][40][41][42][43][44][45][46] characterize the compression hardening properties of the materials. 34,35 For bicontinuous hydrogel, a rising trend of E ter /E ini was observed with increasing compression rate (Fig.…”

“…Researchers have utilized network design to address the poor mechanical properties of conventional hydrogels that lead to failure with a focus on increasing extensibility and fractureresistance. [17][18][19] Approaches fall into four main categories: secondary interactions (ionic, [20][21][22] coordination complexes, [23][24][25] hydrogen bonds, [26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] hydrophobic domains [41][42][43][44] ), homogenization, 45,46 high functionality crosslinks, [47][48][49][50][51][52] and interpenetrating networks (IPN) [53][54][55][56][57][58][59][60][61] including double networks.
