Patent number: 9247736Abstract: A multi-layer film for reducing microbial contamination on a surface. The multi-layer film can include a core layer having a first surface and a second surface opposite the first surface, an adhesive layer disposed adjacent the first surface of the core layer, and an antimicrobial layer disposed adjacent the second surface. The antimicrobial layer can include a cross-linked matrix and an antimicrobial agent dispersed within the cross-linked matrix, where the cross-linked matrix is derived from a polymerizable precursor comprising a material selected from the group consisting of a polymerizable monomer, a polymerizable polymer having a molecular weight of about 1,000 or less, and combinations thereof.Type: GrantFiled: December 14, 2006Date of Patent: February 2, 2016Assignee: 3M Innovative Properties CompanyInventors: Caroline M. Ylitalo, Mahfuza B. Ali, Christopher B. Walker, Jr., Gerald R. A. Hofmann, Matthew T. Scholz, Alphonsus V. Pocius, Linda K. M. Olson

Patent number: 8513322Abstract: Polymeric beads and methods of making the polymeric beads are described. The polymeric beads are crosslinked hydrogels or dried hydrogels. The polymeric beads are formed from droplets of a precursor composition that are exposed to radiation. The droplets are totally surrounded by a gas phase. The precursor composition contains a polar solvent and a polymerizable material miscible in the polar solvent. The polymerizable material has an average number of ethylenically unsaturated groups per monomer molecule equal to at least 1.2.Type: GrantFiled: June 7, 2007Date of Patent: August 20, 2013Assignee: 3M Innovative Properties CompanyInventors: Robin E. Wright, Mahfuza B. Ali, Jessica M. Buchholz, Louis C. Haddad, Linda K. M. Olson, Matthew T. Scholz, Narina Y. Stepanova, Michael J. Svarovsky, Richard L. Walter, Caroline M. Ylitalo, Diane R. Wolk, Yifan Zhang

Patent number: 8318282Abstract: A microstructured antimicrobial film, an antimicrobial film assembly, a method of protecting a surface from microbial contamination, and a method of making a microstructured antimicrobial film. The microstructured antimicrobial film can include a substrate having a first side that includes a first major surface, a plurality of microstructured wells defined in the first side of the substrate, and an antimicrobial material positioned within at least some of the plurality of wells. Each of the plurality of wells can be at least partially defined by a base that is spaced a distance from the first major surface of the substrate. The antimicrobial material can be positioned, such that an upper surface of the antimicrobial material is spaced a distance from the first major surface of the substrate. The antimicrobial film assembly can include a roll or a stack of microstructured antimicrobial films.Type: GrantFiled: December 8, 2008Date of Patent: November 27, 2012Assignee: 3M Innovative Properties CompanyInventors: Caroline M. Ylitalo, Paul D. Graham, Linda K. M. Olson, Narina Y. Stepanova, Robin E. Wright

Patent number: 8124169Abstract: An antimicrobial coating system, a film-forming composition, and an antimicrobial film. In some embodiments, the antimicrobial coating system can include a film-forming composition comprising a polymer having an effective molecular weight, and an effective amount of an antimicrobial agent dispersed within the polymer. The film-forming composition can form a water-insoluble, biocidal antimicrobial film when applied to a surface.Type: GrantFiled: December 14, 2006Date of Patent: February 28, 2012Assignee: 3M Innovative Properties CompanyInventors: Caroline M. Ylitalo, Gerald R. A. Hofmann, Mitchell T. Johnson, Linda K. M. Olson, Duane Douglas Fansler
