Cover Story: Mechanically tough polymer composite hydrogels have attracted widespread interest from both scientific and industrial points of view because of their potential applications in various fields. Hydrogels composed of biocompatible polymers are of particular interest. In this study, we found that composite hydrogels composed of chitosan nanofiber (ChsNF), positively charged alumina-coated silica nanoparticles (ac-SiO2), carboxylated poly (vinyl alcohol) (cPVA), and borax were highly stretchable and robust. The network was formed by multiple crosslinking, such as the complexation between borate and cPVA, the ionic complexation between ac-SiO2 and cPVA, and the hydrogen bond between ChsNF and cPVA. This study showed that the combined use of bio-nanofiber and inorganic nanoparticles as reinforcing agents is effective to fabricate robust and highly stretchable composite hydrogels. View this paper
