摘要

声表面波（surface acoustic wave，SAW）气体传感器具有灵敏度高、选择性好、响应时间短以及体积小，携带方便等优点，因而被广泛应用于环境监测、医疗卫生、化学侦检等领域中有毒有害气体的现场实时检测。敏感膜材料的特性是决定SAW传感器性能（如灵敏度、选择性、响应时间、寿命等）的关键因素。本文首先简要介绍了SAW气体传感器的响应原理和对敏感膜材料的要求，然后重点阐述了用于SAW气体传感器的有机聚合物敏感膜材料的研究进展，最后对其研究趋势做出简单预测。

Abstract

Surface acoustic wave (SAW) gas/vapor sensor is widely used in the fields of environmental monitoring

health care and chemical detection to detect toxic and hazardous gases/vapors on-site and real-time for its advantages of high sensitivity

good selectivity

fast response

small size and easy to carry

etc. The characteristics of the sensitive coating materials is the key factor that determine the performance of SAW gas/vapor sensor

such as sensitivity

selectivity

response time and life. In this paper

the principle of SAW sensor response and the requirements for sensitive coating materials were briefly introduced firstly. Then the research progress of the organic polymer coating materials used in SAW sensors was described in detail and a simple prediction for the research trends was made at last.
