| Outline of Final Research Achievements |
In this study, we tried to prepare the transparent composite material where fine silica particles form aggregation with short-range order, and transparent flexible polymer gel fills the interstices between the particles. When the concentration of the fine silica particles to the polymer gel is lower than 15 vol%, the randomly-arranged fine silica particles induced incoherent scattering. Consequently, the composite material becomes cloudy. With increasing the concentration of the fine silica particles, however, the transparence of the composite material becomes higher because of the order formation of the fine silica particles. The order distance and the structure of the fine silica particles can be controlled by adjusting these concentration. Moreover, we found that the transparent composite material has also high mechanical strength which combines flexibility of the gel and high elasticity of the silica fine particles.
