本文报道了一种基于等离子体功能化多壁碳纳米管/聚酰亚胺复合薄膜的新型连续型相对湿度传感器的制备。相对湿度传感器显示出良好的线性度为1.10在一个较宽的湿度范围内，与60 Ω/%RH和响应时间为10分钟的灵敏度。电阻增加与水的吸附与高MWCNT浓度的复合膜的基础上，解释了吸附的水分子和碳纳米管之间的电荷转移。
This paper reports the fabrication of a novel resistive-type relative humidity sensor based on plasma-functionalized MWCNT/Polyimide composite films. The relative humidity sensors shows a good linearity of 1.10 over a wide humidity range, with the sensitivity of 60Omega/%RH and response time of 10 min. The resistance increase with water adsorption of composite films with high MWCNT concentration is explained on the basis of charge transfer between the adsorbed water molecules and the CNTs.
