| Research Abstract |
Nanostructure and transition of polyelectrolyte brush in ionic amphiphilic diblock copolymer monolayer on the water surface were systematically investigated by X-ray reflectivity and p-A isotherm techniques as a function of brush density and salt concentration. The detailed nanostructure change and its conditions were clarified. It was also found that inverse-added salt responsibility of zwitter ionic brush is observed compared to cationic, and anionic brushes. Thermo-responsive polymer brush systems were also established.
