The range of mechanical properties currently available by the new generation of tough hydrogels is vast. In this section, we will relate said mechanical properties with those of commercial materials. This will help to give a clearer perspective of current tough hydrogels and their potential to be engineered for load-bearing applications. In a statistical sense, the majority of tough hydrogels has a fracture energy in between Γ = 2-5 kJ/m 2 , followed by Γ = 5-10 kJ/m 2 and Γ = 10-20 kJ/m 2 (Figure ). Fracture energies exceeding Γ = 20 kJ/m 2 are rare, but have recently been reported as seen in the main section of this review. The wealth of elastic moduli among the tough hydrogels is distributed over a much broader range, six orders of magnitude (Figure ). Regarding the elastic moduli, a much broader distribution is observed with only a small fraction of hydrogels exceeding E = 50 MPa.
