我们报告完全喷墨印刷碳纳米管气体传感器的柔性基板上的乙醇传感特性得到改善。这种传感器的制作通过两个简单的步骤：印刷电极和基于碳纳米管的活性层。碳纳米管用羧酸（COOH）和聚（3，4-乙撑二氧噻吩）聚（苯乙烯磺酸盐）（PEDOT：PSS）官能化。性能分析表明，与氧化的纳米管相比，聚合物包裹的纳米管的传感器的灵敏度显着增强，增强因子大于2.5。此外，注意到聚合物官能化后传感器响应和恢复时间的显着改善，这预示着柔性塑料电路上的完全可印刷环境传感器。(C)2017由Elsevier B. V.出版
We report on fully inkjet printed carbon nanotubes gas sensors on flexible substrates with improved ethanol sensing characteristics. The sensors were fabricated via two simple steps: printing the electrodes and the carbon nanotubes based - active layer. Carbon nanotubes were functionalized with carboxylic acid (COOH) and poly(3,4-ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS). The performance analysis shows a significant enhancement in the sensitivity of the sensor with polymer wrapped nanotubes in comparison with the oxidized nanotubes, with enhancement factors greater than 2.5. Moreover, a remarkable improvement in the sensor response and recovery times after polymer functionalization is noted which bodes well for fully printable environmental sensors on flexible plastic circuits.
