Abstract: The moisture sensing characteristics of three kinds of compounds prepared by quaternized poly(γ-aminpropyltriethoxysilane) were examined. The results showed that the moisture sensors have the sensitivity>103 (30%~90%RH), hysteresis<2%, response time<30s, good selectivity and reusability.

Key words: poly (γ-aminopropyltriethoxysilane), moisture sensor, preparation
