Abstract

---

A series of excellent poly (vinyl alcohol) (PVA)/polymers blend hydrogel membranes were reviewed using different cross-linking types to obtain proper polymeric dressing materials, which have satisfied biocompatibility and sufficient mechanical properties for wound dressing application. The importance of biodegradable–biocompatible synthetic polymers such as; PVA, natural polymers such as; alginate, starch, and chitosan or their derivatives has grown significantly over the last two decades due to their renewable and desirable biological properties. The properties of these polymers for pharmaceutical and biomedical application needs have attracted much attention. Thus, a considered proportion of the population need those polymeric medical applications for drug delivery, wound dressing, artificial cartilage materials, and other medical purposes, where the pressure on alternative polymeric devices in all countries became substantial. The review explores different polymers which have been blended previously in the literature with PVA as wound dressing blended with other polymeric materials, showing the feasibility, property change, and purpose which are behind the blending process with PVA.
