Background:

Designing hydrogels with combined stretchability, strength, and fracture resistance is challenging.
Existing materials often compromise multiple mechanical properties.

Purpose of the Study:

To develop a robust hydrogel network with ultra-high fracture resistance and self-recoverable stretchability.
To investigate a new mechanism for achieving superior mechanical performance in hydrogels.

Main Methods:

Copolymerization of divinyl benzene and acrylamide in micellar solutions.
Formation of a network with dynamic hydrophobic domains and homogeneous hydrophilic crosslinking.

Main Results:

Achieved ultra-high fracture resistance (> 26 kJ m⁻²) and self-recoverable stretchability (100% recovery from 10,200% strain).
Demonstrated superior anti-crack propagation and fatigue resistance (fatigue threshold ≈ 2.5 kJ m⁻²).
Prenotched hydrogels maintained performance under extreme cyclic loading.

Conclusions:

The developed hydrogel network offers a facile approach to creating tough materials.
Homogeneous hydrophobic crosslinking provides a novel mechanism for extreme self-recoverable deformability.
Potential applications in diverse fields requiring robust and deformable materials.
