摘要

将聚苯胺—多壁碳纳米管聚合物沉积于声表面波（SAW）气体传感器的敏感区

形成敏感薄膜

实现了室温下对不同体积分数NO2的检测。研究表明:这种传感器具有很高的敏感性

良好的重复性和低体积分数检测极限。同时

单一聚苯胺薄膜也做了对比测量

实验结果表明:聚苯胺—多壁碳纳米管聚合物敏感膜比单一聚苯胺薄膜具有更高的敏感性和更短的恢复时间。

Abstract

Polyaniline-multi-walled carbon nanotubes（MWCNT）polymer deposited on SAW gas sensor is fabricated for nitrogen dioxide detection.The polymer is deposited onto the sensitive area of a SAW sensor to form an active layer.The sensor is tested on different volume fraction NO2 gas at room temperature.It is observed that the sensor has a high sensitivity

good repeatability and low detection limit.The sensor which has single polyaniline film is also studied.The experimental result confirms that the sensor based on polyaniline-MWCNT film has higher sensitivity and shorter response time than the sensor with single polyaniline film.
