The present application relates to copolymers of N-halamine (HA) and dopamine (DMA) and their method of formation. The HA and DMA are present in the copolymer in a ratio of 0.4:9.6 to 9.6:0.4 (HA: DMA). The copolymers can be used in novel antimicrobial compositions that can be coated, and covalently bonded to surfaces such as metal, plastic, glass, or paint surfaces. The coating provides a rechargeable antimicrobial surface with the treatment of a halogen. The coating thickness and halogen content can be tuned by adjusting the formulation and crosslinking the coating.
