Crosslinker-Free Polyacrylamide Hydrogels Exhibit High Strength, Fracture Resistance, and Reprocessability
Polyacrylamide (PAAm) hydrogels are commonly prepared by incorporating covalent crosslinkers to establish a stable network structure. Here, we report crosslinker-free, high-water-content (>93%) PAAm single-network hydrogels that exhibit unexpectedly high mechanical performances. These hydrogels are prepared from high...
