Polymeric Materials for Protection Against Chemical and Biological Contaminants
Abstract
The objective of this project was to attach N-halamine functional groups to various polymeric materials to be used as oxidizing agents to render the materials biocidal and resistant to chemical agents. The biocidal objective was successfully achieved for the textile materials nylon and polyester, as well as for a water-borne acrylic polyurethane paint and for functionalized polystrene beads to be used for water disinfection in cartridge filters. Activities of the materials against chemical agents remain to be tested. Common features of all of the materials developed are the abilities to stabilize oxidative chlorine for long periods of time, to be regenerated by exposure to aqueous solutions of free chlorine (bleach), and to inactivate pathogenic microorganisms upon surface contact. It is envisioned that the various materials developed in this research project will be useful to the military in a variety of applications such as in defense against biological and chemical agents in medical facilities, barracks, tents, transport vehicles, and water treatment devices.
