1. A process for preparing an antimicrobial and antiviral polymeric material containing cupric oxide and cuprous oxide as an anti-microbial and anti-viral agent responsible for the antimicrobial and antiviral activity of the polymeric material, comprising preparing a polymeric slurry, introducing a plurality of microscopic antimicrobial and antiviral particles to the polymeric slurry, wherein the particles comprise an antimicrobial and antiviral agent consisting of cupric oxide and cuprous oxide, wherein said particles are of a size of between 1 and 10 microns, dispersing the particles in said slurry and then extruding said slurry to form a polymeric material wherein said particles are incorporated in the polymer, wherein a portion of said particles in said polymer are exposed and protruding from the surface of the material and release Cu++ ions when exposed to water or water vapor to provide the antimicrobial and antiviral activity of the polymeric material. |
