微电流型固体电解质二氧化碳气体传感器研究

A Study on Microamperometric Solid-Electrolyte Carbon Dioxide Gas Sensor

】成功地开发研究了一种具有空间网状多孔结构的新型固体聚合物电解质，由其在金微电极上成膜构制的全固态电化学体系，在常温下对ＣＯ２气体有良好的电流响应特性。如此建立的结构一体的微电流型固体电解质ＣＯ２气体传感器，既消除了常规电化学传感器使用流动电解液引发的弊端，又有体积小、结构紧凑、使用方便的独到优点。

A new type of solid polymer electrolyte based on polyacrylonitrile(PAN) dimethylsulfoxide(DMSO) tetrabutylammonium perchlorate(TABP) system has been developed.The full solid state microamperometric carbon dioxide gas sensor contains two coplanar electrodes coated by a thin layer of PAN DMSO TBAP solid-electrolyte:an Au microdisk as working electrode and an Ag ring counter/reference electrode.It shows good response characteristics for direct amperometric determination of the CO 2 concentration in the gas phase at room temperature.The twoelectrodes possess their own original advantages.
