摘要：
Poly(ethyleneimine) has been applied as a chemical interface for carbon dioxide on a 40 MHz surface acoustic wave (SAW) chemical sensor. The response to carbon dioxide was observed along with degradation phenomena and a strong interference from water vapour. The latter seems possible for the development of a sensor for relative humidity. More experiments are needed to work out this possibility. © 1990.
