Exceptional Mechanical Properties of Phase-Separation-Free Mo3Se3--Chain-Reinforced Hydrogel Prepared by Polymer Wrapping Process.

As Mo3Se3- chain nanowires have dimensions comparable to those of natural hydrogel chains (molecular-level diameters of ~0.6 nm and lengths of several micrometers) and excellent mechanical strength and flexibility, they have large potential to reinforce hydrogels and improve their mechanical properties. When a Mo3Se3--chain-nanowire-gelatin composite hydrogel is prepared simply by mixing Mo3Se3- nanowires with gelatin, phase separation of the Mo3Se3- nanowires from the gelatin matrix occurs in the micro-network, providing only small improvements in their mechanical properties. In contrast, when the surface of the Mo3Se3- nanowire is wrapped with the gelatin polymer, the chemical compatibility of the Mo3Se3- nanowire with the gelatin matrix is significantly improved, which enables the fabrication of a phase-separation-free Mo3Se3--reinforced gelatin hydrogel. The composite gelatin hydrogel exhibits significantly improved mechanical properties, including a tensile strength of 27.6 kPa, fracture toughness of 26.9 kJ/m3, and elastic modulus of 54.8 kPa, which are 367 %, 868 %, and 378 % higher than those of the pure gelatin hydrogel, respectively. Furthermore, the amount of Mo3Se3- nanowires added in the composite hydrogel is as low as 0.01 wt%. The improvements in the mechanical properties are significantly larger than those for other reported composite hydrogels reinforced with one-dimensional materials.
