Abstract: Provided herein is a solid zwitterionic copolymer comprising repeat units of formulas (I) and (II). Compositions and articles comprising the copolymer are also provided, as are methods of making and using the copolymer. For example, layers of the copolymer find use in protecting a substrate from viral contamination, decreasing, reducing, or inhibiting viral proliferation on a substrate, and deactivating a virus on a substrate.
