B 2 (39): 6708–6713. doi:10.1039/c4tb01194e.2050-750Xhttp://nrs.harvard.edu/urn-3:HUL.InstRepos:13919158Most hydrogels have poor mechanical properties, severely limiting their scope of applications. Here a hybrid hydrogel, consisting of hydrophilic and crystalline polymer networks, achieves an elastic modulus of 5 MPa, a strength of 2.5 MPa, and a fracture energy of 14 000 J m−2, while maintaining physical integrity in concentrated electrolyte solutions.en-USJournal Article2015-01-25Jianyu Li, Zhigang Suo and Joost J.
