将含有内外氢键酸性苯酚、羧酸或苯酚/乙酰氧基混合基团的3种超支化芳香族聚酯涂覆在500 MHz声表面波(SAW)传感器平台上，研究了传感器对神经毒剂模拟物甲基膦酸二甲酯(DMMP)和炸药模拟物二硝基甲苯(DNT)的响应。三种超支化聚酯对DMMP都有很强的反应，其中带有羧酸基的超支化聚酯对DMMP的反应尤为强烈。在所研究的三种聚合物中，带有苯酚基团的超支化聚酯对DNT的响应最好。三种超支化聚酯的DMMP和DNT响应也与超支化SAW传感器聚合物和线型SAW传感器聚合物进行了比较。©2007威利期刊公司《应用理工学院学报》，2008
Three hyperbranched aromatic polyesters carrying both internal and exo-presented hydrogen-bond acidic phenol, carboxylic acid, or mixed phenol/acetoxy groups were coated onto 500 MHz surface acoustic wave (SAW) sensor platforms, and sensor responses to the nerve agent simulant dimethyl methylphosphonate (DMMP) and the explosives simulant dinitrotoluene (DNT) were studied. All three hyperbranched polyesters gave strong responses to DMMP, and the hyperbranched polyester carrying carboxylic acid groups gave a particularly strong response. The hyperbranched polyester carrying phenol groups gave the best response to DNT of the three polymers studied. The DMMP and DNT responses of the three hyperbranched polyesters were also compared with hyperbranched SAW sensor polymers carrying exo-presented phenolic sensor groups only, and also with linear SAW sensor polymers carrying phenolic sensor groups. © 2007 Wiley Periodicals, Inc.
