项目摘要

Title : Development of Electrochemical Gas Sensors based on an Electrical Impedance Characteristics of a Surface-modified ElectrodeElectrochemical gas sensors based on an electrical impedance measurement were investigated. An electrode surface was modified with a thin film which was composed of organic functional material ; change in an electrical impedance property of the probe due to a chemical interaction between the surface film and analytes was utilized as sensory principle.The present study consists from two parts. First, with using a synthetic, molecular-bilayer forming amphiphile, we developed a humidity sensor. A transparent thin multi-bilayer film was fabricated on patterned gold electrodes of interdigitated form. An electrical response to humidity change was obtained by using an automatic impedance analyzer. Response time of the sensor was within several minutes, and the sensor showed a good reproducibility.Next, we synthesized new, bifunctional, long-chain alkanethiols which contain an organic functional group for fabrication of surfaces of electrodes. With using a 18-crown-6 derivative of dialkyl disulfide, an ammonia sensor was developed. A molecular film was adsorbed on a silver electrode surface, and the electrical response was obtained by using an impedance meter. The sensor gave a steady-state response in a few minutes after exposure to a sample gas, and the determination of ammonia gas at around ppm revel was possible. The detection limit was 2 ppm, and interference by organic gases such as benzene and chloroform was not observed.
标题:基于基于电阻抗测量测量的表面修饰电解电化学气体传感器的电阻抗特性的电化学气体传感器的开发。用由有机功能材料组成的薄膜修饰电极表面。由于表面膜和分析物之间的化学相互作用而导致的探针电阻抗特性的变化被用作感觉原理。本研究由两个部分组成。首先,使用合成的分子双层形成两亲物,我们开发了一个湿度传感器。透明的薄薄层薄膜是在互换形式的图案化金电极上制造的。使用自动阻抗分析仪获得了对湿度变化的电响应。传感器的响应时间在几分钟之内,传感器表现出良好的可重复性。接头,我们合成了新的,双功能的长链烷硫醇,其中包含一个有机官能团,用于制造电极表面。通过使用二硫化二硫化二硫化物的18个衍生物,开发了氨传感器。分子膜被吸附在银电极表面上,并使用阻抗计获得电响应。传感器在暴露于样品气体后的几分钟内产生稳态反应,并且可以在ppm巨大的启示下测定氨气。检测极限为2 ppm,没有观察到有机气体(例如苯和氯仿)的干扰。
