Abstract
A copper microparticle with antibacterial and/or biocidal activity, wherein each microparticle has a regular, crystalline and microstructured composition that comprises 5 different copper compounds: Antlerite Cu3+2 (SO4) (OH)4, Brochantite Cu4+2SO4 (OH)6, Chalcantite Cu+2SO4.5H2O, Natrochalcite NaCu2+2 (SO4)2OH.H2O and Hydrated copper sulfate hydroxide Cu3 (SO4)2 (OH)2.4H2O/2CuSO4.Cu (OH)2, with the microparticle having a size of between 5 and 50 μm. A process for preparing copper microparticles with antibacterial and/or biocidal activity. A concentrated polymeric composition (masterbatch) with antibacterial and/or biocidal activity that is incorporated during the extrusion process to molten polymers for forming rigid or flexible products such as fibers, filaments, and sheets. A use of a copper microparticle with antibacterial and/or biocidal activity. A use of a concentrated polymeric composition (masterbatch) with antibacterial and/or biocidal activity.
