Study on the High Conductive Polymer as the Miniaturized Reference Electrode

摘要

The polypyrrole is the high conductive polymer which was coated onto indium tin oxide (ITO) glass substrate by electroplated technique to fabricate a miniaturized reference electrode. Besides, the morphology of the ITO glass reference electrode electroplated with pyrrole has been studied through the instrumental analysis utilizing cyclic voltammetry (CV). Furthermore, the sensing characteristics of the reference electrode have been measured by using commercial instrumental amplifier as the readout circuit. Using the high conductive polymer as miniaturized reference electrode has many advantages such as easy fabrication of coating polymer, without any expensive fabricating equipment, easy carry by the miniaturized technique. Hence, it is suitable for the reference electrode production.
