Polyacrylamide (PAM)/carbon nanodot (C-dot) nanocomposite (NC) hydrogels were successfully prepared by free radical polymerization using C-dots as cross-linkers. The storage modulus and the cross-link density of NC hydrogels compared with the pure PAM hydrogel were greatly enhanced due to strong hydrogen bonding interactions between PAM and C-dots. The swelling ratio of NC hydrogels increased with increasing the C-dot contents. The fracture strength of PAM/C-dot NC hydrogel was 47.5 kPa at a stretch of 2940% when the content of C-dots was 1 wt%. C-dots are an ideal nanomaterial for the preparation of novel NC hydrogels with excellent mechanical properties.
