The introduction of antibacterial and hemostatic hydrogels with good mechanical properties that display desirable impacts on wound healing process is still an unmet essential for clinical wound dressings. Herein, a multifunctional hydrogel PEG-CMC-THB-PRTM was fabricated via a one-pot method combining carboxymethyl chitosan (CMC), 2,3,4-trihydroxybenzaldehyde (THB), protamine (PRTM) and 4-arm polyethylene glycol aldehyde (PEG). The hydrogel was formed by the dynamic Schiff base reaction between amino groups of carboxymethyl chitosan and aldehyde groups of 4-arm polyethylene glycol aldehyde and exhibited excellent mechanical properties. The developed hydrogel also showed outstanding effects on anti-bacteria and hemostasis through the release of PRTM. Moreover, the hydrogel could promote extracellular matrix formation and wound closure in vivo, thereby accelerating the healing of skin wound. These results suggested that the multifunctional PEG-CMC-THB-PRTM hydrogel is a promising candidate for the clinical treatment of full-thickness wounds.
