SMALL ELECTRODE SYSTEM FOR ELECTROCHEMICAL MEASUREMENT WITH OPTICAL MICROSCOPIC OBSERVATION FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a small electrode system for electrochemical measurement with an optical microscopic observation function with a simple structure, capable of performing electrochemical measurement of any small targeted area of a material surface and performing simultaneous observation of the small targeted area during the electrochemical measurement of an electrode surface.;SOLUTION: In a measurement method that performs electrochemical measurement and optical microscopic observation at the same time, a small electrode system has a liquid reservoir that has an electrode area of 0.0008 cm² or smaller and in which a water-dipped objective lens is arranged, a coating on the periphery of an electrode surface is composed of a combination of two or more kinds of insulators, and the maximum thickness of the coating is 100 μm or less. As for the coating, pieces of a coating adhesive tape, composed of an adhesive tape and a hardening resin, are placed opposite to each other 200 μm or less apart. It is preferable that the space between the pieces is filled with the hardening resin or that the brightness L* with the adhesive tape placed on the electrode material surface is 60 or less.;COPYRIGHT: (C)2012,JPO&INPIT
