摘要:
以乙二胺为核通过Michael加成和酰胺化缩合反应合成了0.5 ～4.0代的聚酰胺树形分子,采用核磁共振(NMR)、红外光谱(FI-IR)进行了结构表征,并将其作为敏感材料与QCM(石英晶体微天平)换能器相结合构建谐振式甲醛传感器.研究表明:由于该树状分子表面富氨基官能团,对甲醛有着良好的特异性响应,其高度的黏性,也使其能稳定地在QCM表面成膜,经过反复测定,该传感器具有高度的重复稳定性.
Abstract:
Polyamide dendrimers of generation 0.5-4.0 were synthesized by Michael addition and amidation condensation reactions with ethylenediamine as the nucleus, and their structures were characterized by nuclear magnetic resonance (NMR) and infrared spectroscopy (FI-IR). As a sensitive material combined with a QCM (quartz crystal microbalance) transducer to construct a resonant formaldehyde sensor. Studies have shown that due to the rich amino functional groups on the surface of the dendrimer, it has a good specific response to formaldehyde, and its high viscosity, It also makes it possible to stably form a film on the surface of the QCM. After repeated measurements, the sensor has a high degree of repeat stability.
