Modification of surfaces with polymers
First Claim
1. A method of altering the biocidal activity of a surface, comprising:
- applying a polymer in solution to a surface, wherein the polymer comprises covalently attached groups that can be modified to form a radical and covalently attached biocidally active groups, after applying the solution to the surface, applying energy to the solution to form radicals wherein the radicals react with a group on the surface to tether the polymer from the solution to the surface, wherein at least one of the biocidally active groups of the polymer is selected from the group consisting of a quaternary salt, an electrolyte, a betaine, a sulfonate, a phosphonate, a chloramine, and a porphryin.

Abstract
A polymer formed by controlled radical polymerization includes groups that can be modified after controlled radical polymerization to form a radical. The polymer can be the reaction product of a controlled radical polymerization of radically polymerizable monomers, wherein at least one of the radically polymerizable monomers includes at least one group that can be modified after the controlled radical polymerization to form a radical. A compound includes a first group that is stimulated upon application of energy to the molecule to tether the molecule to a surface or to another polymer chain and a second group comprising a controlled radical polymerization initiator functionality. A block copolymer includes at least a first segment to impart a predetermined functionality to a target surface and at least a second segment including functional groups to interact with the targeted surface to attach the block copolymer to the surface. The first segment can free of functional groups that interact with the surface to attach the block copolymer to the surface.
