Hydrogels, which are water-rich cross-linked polymeric networks, have been widely used in various applications such as scaffolds for tissue engineering, vehicles for drug delivery, and model extracellular matrices for biological studies. Nonetheless, the scope of hydrogel applications is severely limited because of their insufficient mechanical performances. To develop strong and tough hydrogels, a preparation of double network hydrogels has been recently proposed, and attracted considerable attention. Particularly, a combination of alginate/polyacrylamide hydrogel has been extensively studied due to its high toughness and excellent biocompatibility. To further improve the mechanical performances of the double network hydrogel, in the current study, cellulose nanocrystal (CNC) was incorporated and then the mechanical and rheological properties of the nanocomposite hydrogels were evaluated in terms of the filler loading. |
