AI Technical Summary
Existing wound dressings are prone to causing pain and secondary injury when changed, and it is difficult to achieve painless changes during wound healing. They also lack effective adhesion and biocompatibility.
Asymmetric nanofiber membranes were prepared by configuring polylactic acid electrospinning solution and gelatin-salamander mixed spinning solution. The polylactic acid outer layer isolates moisture and bacteria, while the gelatin inner layer adheres strongly to the wound. Combined with thermopressing technology, a self-adhesive dressing is formed. The gelatin layer can be decomposed after repair, enabling painless replacement.
It achieves self-adhesion and painless replacement of wound dressings, promotes tissue regeneration, has good biocompatibility and antibacterial properties, avoids secondary damage and pain, and is suitable for dynamic wound management.
