摘要
敏感膜材料的制备直接影响到了传感器的检测性能。本文通过SAW瓦斯传感器的穴番-A敏感膜的制备条件的优化,以改善传感器性能。本文对敏感膜制备过程进行深入分析,特别是实验分析穴番A溶液的浓度以及其与交联剂的配比对传感器响应的影响。研究发现,当穴番-A的浓度为1.5mg/m L,穴番与交联剂混合溶液配比为20:1时,可得到白色均匀晶体状敏感膜,对5%的甲烷检测响应可达1500Hz,比之前研究的SAW瓦斯传感器(响应为1000Hz)性能大大提高,且过程可重复。上述的规律为基于穴番-A的SAW瓦斯传感器性能优化提供了有力的依据。
Coating sensitive film influences the performance of sensor greatly. This paper improves sensor's performance by optimizing the coating conditions. This paper carries on through analysis of coating process, especially giving different concentrations and proportions of solution to conduct experiments. This paper based on the morphology of sensitive film and experiments results, then optimizes solution concentration gradually. The study finds that when the concentration of cryptophane-A solution is 1.5 mg/m L, and the proportion is 20:1, it could obtain uniform white crystal sensitive film. What's more, it achieves 1500 Hz response for 5% methane. Compared with previous research results(response got 1000Hz), its performance increases greatly and this process is repeatable. The revealed laws above mentioned provide the precious basis for optimizing the performance of SAW methane sensor.
