摘　　要：应用硅氢化反应将具有氢键酸性的间三氟甲基苯酚接枝在聚甲基氢硅氧烷上,合成了一种用于有机磷化合物检测的新型氢键酸性敏感材料,并通过IR1、HNMR、GPC和GC-MS进行表征。在此基础上,制备了声表面波(SAW)气体传感器,并对甲基膦酸二甲酯(DMMP)进行了检测,效果良好。A kind of novel grafted hydrogen-bond acidic polymers for surface acoustic wave （SAW） sensor applications were prepared by functionalizing polymethylhydrosilanes with m-trifluoromethyl-phenol groups. The sensor polymer and related intermediate structures were confirmed by IR,^1HNMR, GPC and GC-MS as appropriate. The grafted hydrogen-bond acidic polymers were coated onto the 200 MHz SAW platforms and their responses to the dimethyl mcthylphosphonate （DMMP） were studied.
