Mechanical properties of DN hydrogels: tensile strength, elongation at break, elastic modulus, and fracture energy. The error associated with the presented values is the standard deviation of the five valid tests.
| Mechanical properties | Hydrogel samples |
|
|---|---|---|
| Control | H25_2 | |
| Tensile strength (kPa) | 165.4 ± 7.5 | 165.7 ± 15.7 |
| Elongation at break (mm mm−1) | 23.5 ± 2.2 | 27.9 ± 3.9 |
| Elastic modulus (kPa) | 53.4 ± 5.9 | 56.2 ± 3.5 |
| Fracture energy (J m−2) | 6026.2 ± 649 | 6604.4 ± 557 |
