摘要

研究了基于导电聚合物的气体传感器，重点研究了其在氨气环境中的电阻变化。首先考察了这些装置在制造后在空气中的阻力增加情况，然后考察了它们在不同浓度的氨气中暴露后的阻力变化情况。本文对这些现象以及电化学聚合法制备的聚合物膜的固化方法进行了描述和研究。本文的主要课题是在设计一套精确的浓度测量系统时，在对这类装置的响应进行信号处理时应注意哪些问题。

Behaviour of electroconductive polyaniline films used in highly sensitive ammonia sensors

Electroconductive polymer based gas sensors have been investigated focusing on the resistance changes when exposing them to an ammonia atmosphere. At first, the resistance increase of these devices in air after manufacturing then, the changes in resistance after exposing them to ammonia of different concentration were examined. These phenomena and also the curing method of the polymer film prepared by electrochemical polymerisation are described and examined here. The main topic of this paper is what kind of problems we must face during signal processing of the responses given by this type of device when designing an accurate concentration measuring system.
