Effect of molybdenum disulfide (MoS2) on the preparation of composite hydrogels has been newly demonstrated. The MoS2 nanoplatelet was found to generate radical species with persulfates for initiating polymerization of acrylic monomers and to provide physical cross-linking points for the formation of hydrogel network. In particular, the addition of MoS2 caused more rigid and elastic networks when compared to control hydrogels with a chemical cross-linker, and the resultant nanocomposites were able to exhibit self-healing properties upon heating owing to the reversible, noncovalent network. This synthetic approach would pave the way for the modular design of nanocomposite hydrogels.
