Visualization of Distribution of Electrostatic Force in Electrolyte Clarifying Corrosion and Cell Reactions

User Benefits

- Enables measurement and visualization of the distribution of electrostatic force in electrolytes, which had been impossible with conventional scanning probe microscopes. - Can be used in the fields of corrosion protection and batteries, and is expected to be useful in new energy evelopment,beginning with electric vehicle technology.

Introduction

Systems that utilize the electric potential of materials and substances, such as batteries, IC chips, and memory devices, support everyday life. The Kelvin probe force microscope (KPFM) method, which measures the potential of the sample surface, is widely used in scanning probe microscopes (SPM/AFM), but cannot be used in electrolytic solutions in which electrochemical reactions occur. As reported here, the authors established a new EFM-Phase-ZXY measurement method applying the electrostatic force microscope (EFM) and successfully visualized the distribution of electrostatic force of samples in electrolytes.
