摘要

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.
