Outline of Final Research Achievements |
Three-dimensional scanning force microscopy (3D-SFM) allows us to visualize 3D distributions of hydration structures and flexible surface structures at solid-liquid interfaces with subnanometer-scale resolution. However, its imaging speed was limited to 1 min/image and hence its applications to the investigations on dynamic processes or complicated surface structures were also limited. In this study, we enhanced the imaging speed of 3D-SFM by 10 fold and achieved subnanometer-scale 3D imaging at 5 s/image. In addition, we applied the developed system to investigate 3D molecular adsorption structures of lubricants for hard disks and anti-freezing surfactants for car coolants and obtained important insights into the understanding of the mechanisms of these functional molecules.
