Structure Analysis of Nanoparticles Dispersed in Transparent Resin Using Synchrotron X-ray Scattering

Abstract

In the fields of optical materials such as flat panel displays, transparent resins must show a low thermal expansion and a high heat resistance. In this study, a transparent resin with a low thermal expansion has been successfully prepared by dispersing a high content of colloidal silica into the resin. The measurement of synchrotron radiation small-angle X-ray scattering indicated that the silica particles of a high content in the resin were uniformly arranged in the packing structure predicted by the paracrystal theory. These results suggest that a highly regular arrangement of silica particles may lead to an increase in the light transmittance of the resins.
