Polymer-based composite beads comprised of metal-organic frameworks and metal oxides for toxic chemical removal

Abstract

A polymer-based material includes a polymeric binder and one or more porous active materials that adsorb, chemisorb, decompose, or a combination thereof, a hazardous chemical. The polymeric binder and the one or more porous active materials are combined to form a composite bead. The polymeric binder may include a polyurethane or a styrene-based block copolymer. The porous active materials may comprise metal-organic frameworks, metal oxides, metal hydroxides, and metal hydrates. The one or more porous active materials may be between 1 and 99 wt % of a total composite mass of the composite bead. Alternatively, the one or more porous active materials may be between 80 and 95 wt % of a total composite mass of the composite bead. The hazardous chemical may include a chemical warfare agent, a simulant of chemical warfare agents, and toxic industrial chemicals.
