In order to accelerate hemostasis

prevent bacterial infection and promote wound healing

wound dressing materials should be applied immediately when skin is damaged. In this paper

on the basis of the classification of the wounds and the choice of dressings

the production

drying and molding technologies of wound dressing materials as well as methods of drug loading are introduced. Meanwhile

we summarize the studies on the natural polymer and synthetic polymer wound dressing materials. Natural polymer has been used to heal defect of tissues and skins caused by burns and wounds

because of its good biological compatibility and biodegradability. And synthetic polymer has many advantages

such as long shelf-life

strong mechanical properties and low inflammatory response

and has almost no risks which carries and spreads bacteria. Nowadays

modified natural polymer

synthetic polymer and their composites are being paid more and more attention in the fields of biomedicine and material science. In the future

the researches and applications of wound dressings will be greatly promoted by the development of nanotechnology and controlled delivery technology.
