Researchers from City College of New York, led by Fulbright chemist and scholar Teresa J. Bandosz, have developed intelligent textiles that can be quickly identified and neutralized. nerve.

The fabric consists of a cotton backbone modified by Cu-BTC MOF / graphitic carbon nitride composites. The composite material was previously developed in the laboratory and tested as a detoxifying agent of neurotoxic agent and color detector.

The combination of Cu-BTC and g-C3N4-ox leads to the formation of nanocomposite composite (MOFgCNox) with homogeneous hollows and homogeneous chemistry. After depositing MOFgCNox on cotton weaving material, we obtain a stable fabric with the highest photocatalytic deoxidation potential towards the substitute for the toxic gas neuronal dimethyl chlorophosphate.

The detoxification process is accompanied by visible and gradual color changes, which Bandosz says can be used to selectively select the agents of chemical warfare and to monitor permeability. inside the protective layer.

"This smart textile material absorbs almost 7 grams of chemical warfare agent / detoxifying products per gram of copper. Preeminent performance is related to the high dispersion of MOF crystals on the fiber and the surface structure characterizing the availability of co-centric centers.

Her research team includes Dimitrios A. Giannakoudakis, PhD student; Yuping Hu, guest speaker from China; and postdoctoral researcher Marc Florent. Their research is published in the journal Nanoscale Horizons.
