The bandages should not only protect the wound from infection, but as well promote the healing process, irrigate the wound, absorb the wound secretions, achieve the desired pH of the wound medium, carry active compounds into the wound. For the first time, the regenerated cellulose hydrogel was used for the preparation of wound dressing material. It has been shown that the structure and the properties of regenerated cellulose could be easily modified by the lyophilisation or treating with supercritical CO2. Cellulose – natural, non-irritant, nontoxic, biocompatible, environmentally friendly polymer.
