Hydrophilicity-Graded Trilayered Nanofiber Patch With Keratin-Activated Hemostatic Interface for Sequential Hemorrhage Control and Wound Healing.
We have developed a trilayered nanofiber composite (KTP) via successive electrospinning, engineered with hydrophilicity gradients supporting rapid hemostasis and wound healing. The innermost hydrophilic keratin-PVA layer initiated clotting, middle TEOS-PVA coaxial layer enhanced hemostatic efficacy, and outer PVDF laye...
