摘要
用聚丙烯腈（ＰＡＮ）、二甲亚砜（ＤＭＳＯ）和高氯酸四丁基铵（ＴＢＡＰ）制备了一种新型固体聚合物电解质．以恰当用量配比的ＰＡＮ－ＤＭＳＯ－ＴＢＡＰ聚合物电解质呈有高达１０－４Ｓ·ｃｍ－１的室温离子电导率和好的空间网状多孔结构，由其在金微电极上成膜构成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．如此构型一体的全新的电流型ＣＯ２气体传感器，既消除了传统电化学传感器因电解液渗漏或干涸带来的弊端，又具有体积小。
A new type of solid polymer electrolyte based on polyacrylonitrile (PAN) dimethylsulfoxide(DMSO) tetrabutylammonium perchlorate(TBAP) system has been prepared.The ionic conductivities of such solid electrolytes reach values as high as 10 -4 S·cm -1 at room temperature.At proper content of each component in the solid electrolyte the polymeric film has a porous network microstructure of three dimensions,and exhibits a good level of mechanical properties and dimensional stability.The full solid state electrochemical cell contains two coplanar electrodes coated by a thin layer of PAN DMSO TBAP solid electrolyte:a Au microdisk as working electrode and a Ag ring counter/reference electrode.This study has shown that the integrated two electrode assembly can be directly used for the amperometric solid state carbon dioxide gas sensor devices,and it shows good response characteristics for direct amperometric determination of the CO 2 concentration in the gas phase.Also,such full solid state amperometric sensor devices possess their own original advantages.
