Title: N-halamine Antimicrobial Polymeric Biomaterials

Abstract: Microorganisms such as bacteria, viruses, and fungi are closely related to human life and exist everywhere. Some of them are beneficial and the others are harmful. Infectious diseases are caused by pathogenic microorganisms, which have seriously threatened people’s lives and health. Therefore, the development of antimicrobial materials which can effectively control and eliminate harmful bacteria and viruses is highly desired. N-halamine antibacterial materials have great potential value in applications due to their excellent biocidal efficacies against a broad spectrum of microorganisms, durability, rechargeability, and being environmentally friendly. Our study centers on the molecular design, synthesis, and application of antimicrobial compounds in N-halamine-based polymeric materials for protective materials, water/air filtration, and biomedical materials. A series of N-halamine precursors with different functional groups were synthsized, and attached or incoorperated onto substrates to produce novel rechargeable antimicrobial polymeric biomaterials by different approaches. The N-halamine-based materials showed good antibacterial efficacies against S.aureus and E.coli within short cotact time. The results from the study will be very helpful to expand the N-halamine antibacterial materials to organic/inorganic hybrid antibacterial materials and antimicrobial biopolymers from renewable resources for potential differenct applications.
