Outline of Final Research Achievements

When we utilize nano-materials in various fields, we have to characterize the nano-materials by the light scattering technique to control the quality and safety of the materials. Because the nano-materials recently produced have complex nano-structures, the light scattering technique must be refined to apply to such complex nano-structured materials. The present study was undertaken to establish the refined method of the light scattering technique, and to apply the method to the following self-assembled polymer and low-molar mass surfactant nano-materials: (1) solutions containing fast and slow relaxation components revealed by dynamic light scattering; (2) phase-separating solutions containing colloidal particles of the coexisting concentrated phase; (3) solutions of reverse micelle with nano-sized water pool; (4) solutions of the flower micelle and flower necklace formed by an amphiphilic alternating copolymer.
