The use of traditional dressings,such as gauze,cotton and bandages,has been gradually reduced in medical practice due to their disadvantages,including poor permeability and the tendency to cause secondary injuries during replacement.In contrast,functional hydrogels have attracted much attention due to their excellent biocompatibility,high water retention,ease of introduction of functional components and accelerated wound healing.This paper describes the mechanisms of skin wound healing and the properties of different types of wound dressings.It summarizes the research progress in functional hydrogels constructed by physical or chemical crosslinking over the past five years.Additionally,it offers insights into the future development trends of functional hydrogels.
