A process for preparing an antimicrobial and antiviral polymeric material containing a Cu++ releasing powder 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 panicles comprise an antimicrobial and antiviral particles consisting of as Cu++ releasing powder, wherein said particles are of a size less than 20 microns,
- dispersing the particles in said slurry and then extruding said slurry to form a polymeric material wherein said particles are incorporated in the polymeric material, wherein a portion of said particles in said polymeric material are exposed and protruding from the surface of the polymeric material and release Cu++ ions when exposed to water or water vapor to provide the antimicrobial and antiviral activity of the polymeric material.
A process for preparing an antimicrobial and antiviral polymeric material containing a Cu++ releasing powder 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 water insoluble particles into the polymeric slurry, wherein said particles comprise an antimicrobial and antiviral agent consisting of a Cu++ releasing powder, and wherein said particles have a size of less than 20 microns and are introduced in an amount that is between 0.25 and 10% of the polymer weight,
- dispersing the particles in said slurry, and then
- extruding said slurry to form a polymeric material, wherein said particles are incorporated in the polymer, and 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.
A process for preparing an antimicrobial and antiviral polymeric material, comprising:
- preparing a polymeric slurry,
- introducing a Cu++ releasing antibacterial agent and wherein said particles have a size in the range of less than 20 microns and are introduced in an amount that is between 0.25 and 10% of the polymer weight,
- dispersing the particles in said polymeric slurry, and then
- extruding said slurry to form a polymeric material wherein said particles are incorporated in the polymer, and 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.
A process for preparing an antimicrobial polymeric material, comprising preparing a polymeric slurry, adding Cu-releasing copper oxide particles as an antimicrobial component, wherein said particles are of a size of less than 20 microns and are added in an amount that is between 0.25 and 10% of the polymer weight, 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.
