Abstract
A coating composition comprises an aqueous solution comprising at least one vinyl carboxylic acid monomer and at least one neutral monomer, wherein the at least one neutral monomer has a glass transition temperature of less than about 100° C. in homopolymeric form. A device comprises a protonated polyacrylate coating, wherein the device is inherently antimicrobial, anti-thrombogenic, flexible, and/or sheds few to no particulates.
Claims13
A method of coating a surface of a device, the method comprising:
- applying at least one water soluble vinyl carboxylic acid monomer to the device;
- applying at least one water soluble neutral monomer to the device, wherein the at least one water soluble neutral monomer has a glass transition temperature of less than about 100° C. in homopolymeric form;
- graft-polymerizing a copolymer comprising the at least one vinyl carboxylic acid monomer and the at least one neutral monomer onto the device;
- and
- protonating the vinyl carboxylic acid monomer in the graft-polymerized copolymer.
