SELECTIVE DETECTION METHOD OF NERVE GAS ANALOG IN SOLUTION AND EMBEDDED IN PAPER AND NANOFIBER USING FLUORESCENCE CHANGE OF CONJUGATED POLYQUINOXALINE

摘要

A quinoxaline-based polymer compound according to the present invention is connected to a phenylene or fluorene unit to selectively detect diethylchlorophosphate (DCP) by using the characteristics of fluorescence change induced by chemical interaction between a quinoxaline unit and diethylchlorophosphate (DCP). More particularly, a paper strip sensor using a paper filter sheet to not only detect polymers in solution but also detect polymers in solid phase is manufactured and a fluorescent nonwoven fabric is manufactured via electrospinning using poly(methyl methacrylate) (PMMA) and polyethylene oxide (PEO) as matrix polymers so as to be applied to various sensor materials owing to the flexibility, portability and processability of the paper and the nonwoven fabric. The sensor materials have properties fitting the functions of sensors such as responsivity and selectivity to diethylchlorophosphate (DCP) using the responsivity of quinoxaline to DCP. Therefore, the sensor materials can be applied to sensor materials capable of compounds having structures similar to the structure of nerve gas.;COPYRIGHT KIPO 2015
