将单壁碳纳米管（SWCNT）与分子印迹粉末（MIP）混合，制备了SWCNT-MIP复合材料。采用XRD和TEM对样品的结构和形貌进行了表征。以氧化铝管为基底，以Au电极和Pt丝为电极，制备了SWCNT-MIP复合材料气敏元件，并通过间接加热法测试了其气敏性能。结果表明，SWCNTs-MIPs为正交钙钛矿结构，平均粒径为10-30 nm。单壁碳纳米管分子印迹聚合物具有良好的甲醇气敏性能。在90 °C下，对1 ppm甲醇的响应为19.7，对其他惰性气体（乙醇、甲醛、甲苯、丙酮、氨和汽油）的响应低于5。响应时间和恢复时间分别为50和58 s。所制备的单壁碳纳米管分子印迹聚合物对低浓度甲醇具有良好的选择性和响应性
The single-walled carbon nanotube (SWCNT)-molecularly imprinted powder (MIP) composites in this paper were prepared by mixing SWCNTs with MIPs. The structure and micrograph of the as-prepared SWCNTs-MIPs samples were characterized by XRD and TEM. The gas-sensing properties were tested through indirect-heating sensors based on SWCNT-MIP composites fabricating on an alumina tube with Au electrodes and Pt wires. The results showed that the structure of SWCNTs-MIPs is of orthogonal perovskite and the average particle size of the SWCNTs-MIPs was in the range of 10–30 nm. SWCNTs-MIPs exhibit good methanol gas-sensitive properties. At 90 °C, the response to 1 ppm methanol is 19.7, and the response to the interferent is lower than 5 to the other interferent gases (ethanol, formaldehyde, toluene, acetone, ammonia, and gasoline). The response time and recovery time are 50 and 58 s, respectively. The as prepared SWCNTs-MIPs possesses good selectivity and high response to low concentrationmethanol
