چکیده مقاله
Nerve agents are considered the most nefarious of synthetic chemical derivatives. They are potent acetylcholinesterase (AChE) active agents, clearly differentiated from other chemical warfare (CW) type agents (blister, blood, choking, incapacitating, tear and vomit agents) because of their phosphorylating mode of action, derived from their organophosphonate structure. Specifically, this unique structure is the key to its danger expressed by mammalian toxicity nerve agents compared with similar related species (vide infra)[1]. The purpose of this study is to understand and to evaluate the adsorption abilities of electrospun composite nanofibrous against nerve gas simulant dimethyl methylphosphonate (DMMP) along with trimethyl phosphate (TMP), methyl dichlorophosphate (MDCP), and trichlorophosphate (TCP) and assess the possibility of using the electrospun nanofibers as protective membranes in face masks and warfare clothing [2]. Adsorption of stimulants of organophosphonate, was investigated on the surface of PAN nanofibrous embedded with Schiff-base. The result showed the role of modified PAN nanofibrous with schiff-base on the effective adsorption of organophosphonate, as a stimulant of nerve agents, and possesses a suitable candidate for protecting cloth. The surface morphology and other properties of the PAN/Schiff-base composite nanofibrous are characterized by various techniques, including SEM, TEM, FT-IR, TGA and UV-vis spectroscopy.
