New fabric neutralizes the effects of chemical weapons

Scientists at North Carolina State University have developed a way to attach a lightweight coating to clothing that can neutralize toxins.

Chemists have begun to study zirconium-based organometallic frameworks (MOFs), which destroy harmful compounds. MOFs are small, porous structures that absorb vast amounts of gases and other substances. Zirconium helps to neutralize toxic materials. However, MOF can take a long time to create. Also, most MOF powders are unstable and extremely difficult to apply to clothing. In a new study, the researchers decided to test if they could “grow” MOF on fabric at room temperature, creating a lightweight shield that can be used on protective clothing.

Based on previous research, the scientists combined polypropylene with a MOF mixture based on zirconium, a solvent and two binders. To distribute the coating evenly over the fabric, chemists treated it with a thin layer of aluminum, titanium and zinc oxide. The researchers then tested this combination with dimethyl-4-nitrophenyl phosphate (DMNP), a molecule that reacts like nerve agents. The researchers found that MOF-treated tissues inactivated DMNP in less than five minutes. It is noted that the new technology can be applied in the manufacture of clothing for soldiers and rescue services.
