Research Advances in Electrospun Fibers as Dressingsfor Poor-healing Wound

As an advanced type of functional material, electrostatic spinning wound dressing is characterized by high surface area, high porosity andgood biological properties. Compared with other types of dressings, it not only allows cell respiration and prevents bacterial infection of the wound, butalso stimulates the growth of skin cells and enhances the healing process, indicating a new direction for the research and development of future wounddressings. This article introduced the principles and characteristics of electrospun nanofibers with special focus on the application progresses of differenttypes of polymers and biologically active substances in the preparation of electrostatic spinning wound dressings.
