Chemical weapons? Tall fabric coating technology to solve

China Coatings Online News:
newly developed fabric coating can mediat the poison of chemical weapons and help save countless lives.
Following our previous introduction to the amazing technological innovation of using "metal-organic skeleton" (MOF) materials to extract water from the desert, here is a second introduction to the life-saving innovations of foreign scientists using this material's new powder coating for fabric products to medium toxic chemicals.
scientists report that they have developed a way to attach a lightweight powder coating to the fabric that can contain toxins used in chemical weapons that poison the human body through the skin.
new life-saving technology could eventually be used to protect soldiers and emergency workers.
the study has been published in the Journal of the American Chemical Society (ACS).
chemical weapons were first used extensively in World War I, and dozens of deadly potential chemical weapons have been developed since then.
, scientists have begun exploring the use of zirconium-based "metal-organic skeleton" (MOF) powders to degrade and destroy harmful compounds in toxic gases.
MOF is a tiny porous structural substance whose large surface area allows them to absorb large amounts of gas and other substances, while radon helps to between toxic substances.
but large-scale production of MOF materials is still difficult because of the high temperature and long reaction time required. In addition, most MOF powders are unstable and combining them with clothing fabrics has proven challenging.
, Dennis Lee, Gregory N. Parsons and colleagues tried to "grow" MOF on fabrics at room temperature, creating lightweight "shields" that could be used in uniforms and protective clothing.
based on previous research, scientists exposed polypropylene, a nonwoven material commonly used in reusable shopping bags and some clothing, to a mixture of molybies, solvents and two adhesives.
to ensure that the coating is evenly coated on the fabric, they pre-treat the fabric with a thin layer of aluminum, titanium or zinc oxide.
, they tested the product with nitrobenzene methamphetamine (DMNP), a relatively harmless molecular substance with similar reactivity to sarin, Soman, and other neurotoxins.
found that MOF-treated fabrics catalytically degraded DMNP in less than five minutes, suggesting that this research direction is a viable means of creating chemical weapons protective clothing.
