Abstract

Polyurethane (PU) polymer is widely used in biomedical application. In our study we have combined polyurethane with silver nanoparticles to develop a nanocomposite material for antibacterial medical applications. Such combination has antibacterial properties and control the toxicity too. In current research we have mixed the different sizes and types of silver nanoparticles into the polyurethane matrix. The result was their antibacterial activity, mechanical strength, and biocompatibility. The antibacterial performance of the prepared nanocomposites was evaluated against representative bacterial strains, while their mechanical and biocompatibility characteristics were also examined. The effect of silver nanoparticle incorporation on the structural, morphological, and functional properties of the polyurethane matrix was investigated. Particular emphasis was placed on understanding nanoparticle–polymer interactions and their contribution to the overall performance of the composite material. Although silver nanoparticles are generally toxic, embedding them within the polyurethane matrix reduces their toxicity and allows controlled release of silver ions. Various characterization techniques were used to analyze the structure of the material, including FESEM for surface morphology, FTIR for chemical bonding, and XRD for crystal structure analysis. These results confirmed that silver nanoparticles were uniformly dispersed within the polyurethane matrix and formed interactions with the polymer. Thus, polyurethane–silver nanoparticle composites have the antibacterial capabilities, making them suitable for use in medical devices – such as wound dressings – where infection control and material performance are critical.

Keywords: Polyurethane, sliver nanoparticles, antibacterial, polymer, medical devices, wound dressing.
