- 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.
