Abstract
Hydrophobic polymeric coatings which can be non-covalently applied to solid surfaces such as metals, plastics, glass, polymers, textiles, and other substrates such as fabrics, gauze, bandages, tissues, and other fibers, in the same manner as paint, for example, by brushing, spraying, or dipping, to make the surfaces virucidal and bactericidal, have been developed.
Claims20
A virucidal composition comprising a coating comprising a hydrophobic, water-insoluble polymer deposited on an inert surface, wherein if the polymer is a cationic polymer, the polymer is selected from the group consisting of polymers of Formula I
- wherein R1-R6 are alkyl groups,
- polymers of Formula II
- wherein R1-R3 are alkyl groups, and
- polymers of Formula III,
- wherein R1-R3 are alkyl groups.
