Disease transmitting microorganisms, such as bacteria, viruses and fungi, are the main causes of hospital‐acquired infections (HAI). This is the justification for the development of nanotechnology‐based new materials and, in particular, for the synthesis of antibacterial nanocomposites of the type polymer / antibacterial metal, which create surfaces with a large bacteria inhibiting activity. In the present work, antibacterial polymeric nanocomposites have been created by preparing polyvinyl chloride (PVC) from a resin emulsion as plastisol and synthesizing copper nanoparticles in‐situ within the polymer matrix. The methodology of the process includes the synthesis of a copper precursor, its dispersion by ultrasonic pulses, its stabilization and mixing with other PVC additives, in order to obtain chemical reduction during the gelation of the plastisols. Analysis of the PVC / NPsCu0 ...
