Strong and Rapidly Self‐Healing Hydrogels: Potential Hemostatic Materials

Benzaldehyde‐terminated telechelic four‐armed polyethylene glycol (PEG‐BA) is synthesized and cross‐linked with carboxymethyl chitosan (CMC) to form dynamic hydrogels with strong mechanical performance. The gelation temperature and time, mechanical performance, and self‐healing behaviors are systematically investigated. The hydrogels have good storage modulus up to 3162.06 ± 21.06 Pa, comparable to conventional bulk hydrogels. The separated...
