Abstract

This paper examines the prospects of using polyvinyl alcohol as a unique binding filler, ideally suited for the creation of cutting-edge test materials and wound dressings. The conditions for obtaining polymeric medical films based on polyvinyl alcohol were revealed, as well as the investigation of certain physicochemical properties of the resulting films. The optimal polymer concentration in the solution used for film formation was determined. A composition that incorporates a cross-linking agent and a plasticizer was selected, providing the films with water resistance, elasticity, softness, and flexibility. Water absorption, swelling, and elasticity were assessed for a wide range of film compositions. The potential application of these developed films as long- lasting wound dressings was demonstrated.
