涂敷脲醛树脂的石英晶体微天平湿度传感器
Quartz Crystal Microbalance Coated with Urea Formaldehyde Resin Films Used as Humidity Sensor
摘要
Abstract
This paper reports a novel quartz crystal microbalance ( QCM ) humidity sensor. First, the urea-formaldehyde resin ( UFR) polymer was synthesized in alkaline conditions, and then the polymer was prepared in situ by polymerization on the quartz crystal electrode in acidic conditions to form the sensitive layer of the humidity sensor. The influence of film thickness on the detection of sensitivity, the characteristics of response , repeatability, stability of the sensor were also investigated. Experiment results indicated that the frequency of the sensor coated with UFR film changed significantly with relative humidity, and the newly developed sensor exhibited good reproducibility and stability. The proposed sensor can be applied to detect humidity in practical production.关键词
