| Research Abstract |
Non-surface activity of ionic amphiphilic diblock copolymers, which we found experimentally first in the world, is out of common sense of surface and interface chemistry. We have clarified that this unique property is due to image charge repulsion at the air/water interface and also to stable micelle formation in bulk solution. Furthermore, we have succeed to control the transition between unimer and micelle, and between non-surface active and surface active by external factors such as pH and temperature, which change the balance of ionicity and hydrophobicity of block polymers.
