摘要

提出了一种基于氧化铜/聚苯胺包覆光子晶体光纤的一氧化碳传感器。将标准单模光纤与实心光子晶体光纤熔接形成马赫-曾德尔干涉结构,在光子晶体光纤表面涂覆氧化铜/聚苯胺复合材料,用于检测一氧化碳(CO)。结果表明,在光纤表面形成了一层厚度约为2 μm的均匀复合膜;该传感器的灵敏度为17 pm;传感器在CO体积分数为0~75×10-6的范围内呈现良好的线性关系和选择性,响应时间和恢复时间分别约为80 s和110 s。该传感器具有成本低、结构简单、制作容易等优点。

Abstract

A carbon monoxide (CO) gas sensor based on copper oxide/polyaniline composite membrane-coated photonic crystal fiber is proposed. The Mach-Zehnder interference structure is formed by fusion splicing a standard single-mode fiber to a solid photonic crystal fiber. The copper oxide/polyaniline composite material is coated on the surface of the photonic crystal fiber, and then the purpose of detecting carbon monoxide can be achieved. The results show that a uniform layered film is formed on the surface of the fiber with a thickness of about 2 μm. A high sensitivity of 17 pm and a good linear relationship are achieved in the range of CO volume fraction of 0~75×10-6. The response time and recovery time are 80 s and 110 s, respectively. The sensor has an advantage of low cost, simple structure, and easy to manufacture.
