Microstructured multi-composite copper microparticles with antibacterial and/or biocidal activity comprising five different types of copper compounds

摘要

As copper microparticles having antibacterial and/or biocidal activity, each microparticle is antlerite Cu ₃⁺² (SO ₄ )(OH) ₄ , Brochantite, which are five different copper compounds. ) Cu ₄⁺² SO ₄ (OH) ₆ , Chalcantite Cu ⁺² SO ₄ 5H ₂ O, Natrochalcite NaCu ₂⁺² (SO ₄ ) ₂ OH H ₂ O and hydrated Copper sulfate hydroxide Cu ₃ (SO ₄ ) ₂ (OH) ₂ · 4H ₂ O/2CuSO ₄ · Cu(OH) ₂ comprising a regular, crystalline and microstructured composition comprising 5 It has a size between μm and 50 μm. Process for producing copper microparticles having antibacterial and/or biocidal activity. A concentrated polymer composition (masterbatch) having antimicrobial and/or biocidal activity that is incorporated into the molten polymer during the extrusion process to form rigid or flexible articles such as fibers, filaments, and sheets. Use of copper microparticles with antibacterial and/or biocidal activity. Use of concentrated polymeric compositions (master batches) with antibacterial and/or biocidal activity.
