We have developed tough nanofiber hydrogels incorporating ferritin nanoparticles with a core-shell
structure that is suitable for stress concentration reduction. The swelling properties of the
nanocomposite hydrogel under external forces were enhanced, leading to fast water absorption. The
elastic modulus, tensile strength, and elongation at break of the nanocomposite hydrogel measured
in solutions were dramatically enhanced as compared to those of the bare polymer hydrogel. During
the tensile tests, the strong bonding between the nanofiller and polymer matrix played an important
role in enhancing the toughness of the composite hydrogel fibers.
