The layered nanocomposite hydrogel films containing chitosan (CS) and graphene oxide (GO) have been prepared by water evaporation induced self-assembly and subsequent physical cross-linking in alkaline solution. The layered CS/GO hydrogel films obtained have a nacre-like brick-and-mortar microstructure, which contributes to their excellent mechanical(More)
Self-healing hydrogels like tissues or organs which are repaired automatically in response to damage show great promise. However, it remains a challenge to develop novel functional nanoparticles as crosslinkers to prepare tough and self-healing nanocomposite hydrogels. Here, we report the preparation of water-soluble ultrasmall aluminum hydroxide(More)
