Keywords: Metal Organic Framework, Electrospinning, Nanofibers, Chemical Warfare Agents, Filtration, Chemical Absorbance, Chemical RemediationMetal organic Frameworks (MOFs) are a hybrid advanced material consisting of metal ions and organic molecules that exist as a three-dimension structure. MOFs are known for their high porosity and large surface area to volume ratios, which make them ideal candidates for gas transportation and storage, water absorption, and drug delivery. More specifically, MOFs are extremely effective in the capturing and remediation of harmful chemical warfare agents (CWAs) because of their large capture surface area, catalytic detoxification properties, and the variety of metal ions that can be applied to the organic framework. In order to optimize the MOFs, capture efficiency, MOFs have been dispersed in Electrospun nanofibers to make a specialty high surface area filter to protect against harmful CWAs. To produce a MOF-Nanofiber composite, the MOFs were dispersed in a Poly vinylidene fluoride (PVDF) polymer solution; when electrospun, PVDF is one of the most effective filtering materials because of the nanofibers High surface area to volume ratio and the inherent electrostatic properties of the polymer. These MOF-Nanofiber composite filters applied to gas mask or fabrics to protect against common chemicals, like chlorine and ammonia, or more dangerous CWAs containing phosphate ester bonds.
