TitleSynthesis and characterization of multi-catalyst polyelectrolyte membranes as protective materials for the decomposition of chemical warfare agents
DescriptionThere is an urgent need for the advancement of technology to enable the decomposition of chemical warfare agents (CWA) in an effective and efficient manner. Developing materials that can target a variety of CWA has many challenges. However, the development of novel materials has made possible the emergence of self-decontaminating materials to address this threat. A multi-catalytic polyelectrolyte membrane (MC-PEM) composite has been designed to protect users while decomposing particularly nerve and blister agents. It is comprised of a polyelectrolyte membrane that encloses metal-oxide nanoparticles (MONP) within the substrate and incorporates polyoxometalates (POM) on the surface of the substrate. MONP provide the decomposition of nerve agents via hydrolysis and POM provide the catalytic decomposition of blister agents via photo-oxidation, while also providing colorimetric sensing capabilities. This technology is envisioned to be used as a coating layer within military textiles and other applications that require safety against harmful substances.
