英文摘要：

The wound dressings can protect wounds, control infection and promote wounds healing when skin is damaged. In this paper, firstly, the selection criteria and classification of ideal wound dressings are introduced. Then, the studies on the natural polymer wound dressing materials are summarized according to structural characteristics and applications. Polysaccharides including cellulose, alginates, chitin, chitosan, agar, pectin, gum, glycosaminoglycans and so on can be used as wound dressings. Protein based wound dressings are mainly classified as plant proteins and animal proteins. In the future, the researches and applications of wound dressings will be greatly promoted with the development of polymer synthesis technology and controlled drug delivery technology.
