摘要：
A carbon monoxide gas sensor based on single-walled carbon nanotube (SWCNT) has been developed for detection of carbon monoxide (CO) at room temperature. Copper chloride (CuCl) was mixed with SWNT by mechanical blending. The thin film was deposited on interdigitated electrodes by using airbrush technology. This paper described the fabrication of the sensor for detecting carbon monoxide with concentrations from 20 ppm to 100 ppm. The performance of CO gas sensor was measured by using relevant apparatus to obtain the continuous sensor electric resistance change on exposure to CO and air atmosphere at room temperature, respectively. The results exhibited that the senor presented a larger sensitivity and a good recoverability. The experimental results suggested the potential use of CuCl doped SWCNT for CO detecting.
