Nanocomposite with bactericide activity (Machine-translation by Google Translate, not legally binding)

摘要

Nanocomposite with bactericidal activity. The present invention relates to the synthesis of a new nanocomposite containing metallic nanoparticles of controlled core type size and morphology, inserted and stabilized in an ion exchange matrix formed by polymeric fibers characterized by the presence of functional groups with a pka 4, preferably sulfonic groups. The nucleus of the nanoparticle is formed by a metal with ferromagnetic properties, preferably cobalt, and the coating, by a metal with bactericidal capacity, preferably silver. The ferromagnetic properties allow to collect by magnetic traps the possible nanoparticles that can detach from the nanocomposite, thus avoiding contamination of the treated medium. In addition, thanks to its great bactericidal capacity, it can be used for the decontamination and/or disinfection of different media, such as water.
