碩士 === 國防大學中正理工學院 === 應用化學研究所 === 93 === A prototypical conjugated polymer,polyaniline,was examined for chemosensor application to detect chemical warfare agents such as incapacitating agents and tearing agents simulants.The equilibrium dopping adsorption of chemical agents was analyzed under polyaniline sensor condition by 4-point probe resistivity sheet resistance tester and semiconductor parameter analyzer,sensitive to changes in surface resistance and conductivity. The results of the experiments show that responses to the chemical agent simulants can be achieved with higher semiconductivity samples. In summary,conductivity-based chemosensing method merits attention because of its sensitivity,selectivity and simplicity.The fact that polyaniline showed high conductive sensitivity toward incapacitating agent simulants indicated it is potential candidates chemosensor material for detecting chemical warfare agents.
