Antimicrobial material comprising synergistic combinations of metal oxides

This invention describes a plastic material designed to kill microbes. It works by embedding two specific types of metal oxide powders into the plastic: one where the metal exists in multiple chemical forms (like Ag4O4 or Cu4O4) and another where the metal has only one chemical form (like copper oxide or zinc oxide). When the material gets wet, these different metal compounds interact to create a powerful antimicrobial effect.

Why it matters: Since 2019, a heightened global awareness of surface hygiene and pathogen transmission has emerged, increasing the relevance and potential applications for self-sanitizing materials like this.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModeratePolymer compounding, uniform powder dispersion
