Abstract
Textile fibers at least partially coated with a coating that includes particles of metal-organic frameworks dispersed in a polymeric base are provided. Also provided are fabrics formed from the textile fibers, protective gear and articles of clothing made from the fabrics, and methods of using the fibers and fabrics to catalyze the hydrolysis of organic molecules, such as organophosphate-based nerve agents, having hydrolysable bonds.
Claims18
A textile fiber at least partially coated with a composite, the composite comprising particles comprising metal-organic frameworks that are catalytic for the hydrolysis of an organophosphate compound dispersed in a matrix comprising a polymeric base, wherein the polymeric base comprises a crosslinked hydrogel.
A method of disabling a toxic agent comprising an organophosphate compound having a hydrolysable bond, the method comprising exposing the organophosphate compound to a fabric coated with a composite, the composite comprising particles of metal-organic frameworks that are catalytic for the hydrolysis of the organophosphate compound dispersed in a matrix comprising a polymeric base, wherein the polymeric base comprises a crosslinked hydrogel, in an atmosphere having a relative humidity in the range from 10% to 100%, wherein the metal-organic frameworks catalyze the hydrolysis of the hydrolysable bond in the presence of water vapor absorbed from the atmosphere.
A method of forming an article of clothing, the method comprising:
- applying a coating of a liquid solution comprising metal-organic frameworks that are catalytic for the hydrolysis of an organophosphate and dispersed in a matrix comprising a polymeric base comprising a crosslinked hydrogel to textile fibers in a fabric;
- drying the fabric to remove water and volatile components;
- and
- incorporating the dried fabric into an article of clothing.
