Research Abstract

Block copolymers self-assemble into regular periodic structures of the order of 10-100 nm with various shapes. Therefore, it is expected to use them for the application as nanotechnology materials. For that purpose, the control of their nanostructures is the big problem. In this study we elucidated the mechanism of formation and extinction of the lattice defects and grain-boundary structures by analyzing their structures with a 3D-TEM technique and obtained the most important knowledge on the controlling technique of nanostructures in block copolymers.
