Functionalized polymer nanofibre membranes for protection from chemical warfare stimulants

Functionalized polymer nanofibre membranes for protection from chemical warfare stimulants

A catalyst for the detoxification of nerve agents is synthesized from beta-cyclodextrin (beta-CD) and o-iodosobenzoic acid (IBA). Functionalized polymer nanofibre membranes from PVC polymer are fabricated with beta-CD, IBA, a blend of beta-CD + IBA, and the synthesized catalyst. These functionalized...

description A catalyst for the detoxification of nerve agents is synthesized from beta-cyclodextrin (beta-CD) and o-iodosobenzoic acid (IBA). Functionalized polymer nanofibre membranes from PVC polymer are fabricated with beta-CD, IBA, a blend of beta-CD + IBA, and the synthesized catalyst. These functionalized nanofibres are then tested for the decontamination of paraoxon, a nerve agent stimulant, and it is observed that the stimulant gets hydrolysed. The kinetics of hydrolysis is investigated using UV spectroscopy. The rates of hydrolysis for different organophosphate hydrolyzing agents are compared. The reactivity and amount of adsorption of these catalysts are of higher capacity than the conventionally used activated charcoal. A new design for protective wear is proposed based on the functionalized nanofibre membrane.
