摘　　要：化学传感器的灵敏度和选择性主要通过敏感材料的选择来确定。研究和开发适当的材料使气体传感器的敏感特性达到最优是研究气体传感器的重要步骤。利用1,3双-(2-羟基六氟-2-丙基)-丙烯和表氯醇缩聚制备了一种新型的含磷毒剂敏感膜材料——环氧树脂-B;利用石英晶体微天平(QCM)法对氟多元醇(FPOL)和环氧树脂-B 2种膜材料进行了性能评价,结果表明:新型膜材料环氧树脂-B对含磷毒剂的选择性好、吸附性能力强,是一种可用于野外含磷毒剂实时侦检的实用敏感膜材料。The sensitivity and selectivity of chemical sensors are controlled by sensitive materials mainly. Researching and developing novel sensitive materials are the important progress optimizing chemical sensors. A new sensitive material--epoxy resin-B is prepared by the polyeondensation of 1,3-di （2-hydroxydexafluoro-2- propyl） propene with epichlorohydrin. The properties of both materials of FPOL and the epoxy resin-B are evaluated by quartz crystal mierobalanees （ QCM ）, The result shows that the epoxy resin-B is a sensitive material with high selectivity and adsorbability to toxic organophosphorous vapors and it can be used in field at real-time.
