【摘要】 为获得高灵敏度的纳米结构柔性化学传感器,在柔性的基板上对聚苯胺进行了电化学沉积。通过构筑叉指结构的化学传感器原型器件,并选择代表性气体对其气敏行为进行了表征。结果表明,采用恒电位法制得的聚苯胺薄膜为纳米线结构形貌,XRD结果显示该有机薄膜为高度取向结构。所构筑的化学传感器原型器件室温下对部分代表性的挥发性气氛显示出快速的响应和良好的可逆恢复。这为高灵敏度柔性化学传感器及其阵列提供了一种简便的材料制备途径,也将有助于其它柔性有机电子器件的构筑和应用。更多还原

【Abstract】 To develop a chemical sensor with high sensitivity, the aniline electropolymerization on the flexible substrate was carried out using a programmed constant-voltage method in this paper. A chemical prototype sensor was constructed based on polyaniline film and interdigital golden electrodes. The gas-sensing behavior of the sensor to some typical vapors operating at room temperature was investigated. The SEM results showed nanofiber structure of polyaniline film obtained. The XRD results showed high oriented behavior. At same time, the prototype sensor showed rapid response, and good reversibility. The response time is several seconds. This study would provide a simple approach for preparation of nanostructured materials needed for a flexible chemical sensor or other organic flexible nanoelectronic devices.更多还原
