Abstract

Abstract An asymmetrical wound dressing functions akin to human skin by serving as a protective barrier between a wound and its immediate environment. However, significant challenges persist concerning the robust adhesion and asymmetrical adhesion properties of hydrogels, particularly when applied in emergency hemostasis and wound healing contexts. Herein, the study has successfully synthesized hydrogel patches with Janus asymmetric‐adhesion, denoted as HGO‐C, exclusively comprised of natural polymers. This achievement is realized through the assembly of adhesive hydrogel (HGO) and non‐adhesive hydrogel (CGC), thereby amalgamating their distinct functionalities. The non‐adhesive hydrogel component served as a…
