Abstract
Hydrogel dressings are soft biomaterials that need protection from external influences. Polymer sheets such as breathable film (BF) or breathable laminate (BL) were characterized in respect of water vapor transmission, water contact angle, microbial penetrability, and antimicrobial property to protect hydrogel dressings. The mechanical property and water retention ability of hydogels PVP-CMC and PVP-CMC-BA with and without BF and BL have been examined. Hydrogels covered with either BF or BL show better mechanical flexibility; however, their water retention capacity increases reasonably. The determined efficient properties of polymer sheets established that BF is better than BL as a protective sheet cover for hydrogel dressings.
