Executive Summary : | Chemical warfare agents (CWAs) are constantly used against terrorists and civilians despite a strict restriction on their creation, purchase, and storage. They are simple to disperse in air and water, may wreak huge havoc with a small amount, and are appealing terrorist weapons. In order to detoxify and guard against these dangerous substances, such as Soman and Sarin, effective technologies and garment design are urgently required. Conventional fibre protective gear simply prevents these molecules from penetrating farther, necessitating the usage of an active protective layer that the wearer can utilise as a flexible, air-permeable textile. CWAs are chemically stable and provide a threat to human health when exposed for an extended period of time. Their half-lives range from days to weeks. This makes it more challenging to get rid of these chemicals in a safe manner after each interaction. The creation of self-cleaning protective textile materials has gained significance as a result of the current use of CWAs against civilians. Due to their distinctive configuration of metal nodes and organic linkers within a clearly defined matrix, exceptional internal surface areas, customised structures, tunable pore architectures, and a variety of framework functionalities, a number of MOFs (Metal Organic Frameworks) have been developed specifically for the deactivation process. Regrettably, although being a century old, MOFs' practical use for the detoxification of CWAs is still relevant today because of their poor kinetics, low selectivity, activity, and stability. According to the practical restrictions, there is still opportunity for the creation of de novo MOFs with superior qualities that might be exploited as one of the potential options for the detoxification of CWAs. In light of this, a number of MOFs with clearly defined pore properties will be created using an imidazole-based linker under the auspices of this study. We anticipate that MOFs functionalized by imidazole will thrive in the heterogeneous catalytic system for the detoxification of CWAs by combining the advantages of MOFs and the imidazole group. The fabrics with MOF coatings exhibit outstanding catalytic activity in the hydrolysis of the harmful nerve toxin GD and its commonly used DMNP counterpart. By decreasing the diffusion of CWAs, the MOF layer in the composite prolongs the necessary contact time for the hazardous compounds to break down. The protection time provided by the developed composites would also be substantially longer than that of the parent fabric. Such materials would permit sieving applications, and can be developed as robust active catalytic material that will not only be capable of neutralising stockpiles of toxic CWAs but also be incorporated on the textile/fibre surface to fabricate protective garments and face masks thus allowing the protection to the soldiers and civilians. |
