By using polyacrylate-co-acrylamide and linear polyethylene glycol (PEG) as the first and second networks respectively, the double network hydrogels with mechanical properties of cartilage have thus been prepared by photopolymerization. The successful synthesis of hydrogel is verified by Fourier infrared spectroscopy, with its swelling property calculated by weighing method, followed by a test of its mechanical properties by a universal tensile testing machine. The results show that the stress of the prepared hydrogel is about 1.82 MPa under 304% tensile strain; while under 80% compression strain, the stress is approximately 10.36 MPa, with the hydrogel effectively dissipating energy with high toughness (3.37 MJ/m3). After 10 cycles, the peak stress remains at 99.1% of the initial stress value with a low swelling rate of 2.16. It can be seen that this double network cross-linking condition improves significantly the self-recovery and anti-fatigue properties of the hydrogel, characterized with fine anti-swelling properties, which makes it a new potential cartilage-like material.
