Structural Parameters of Ordered Nanocomposites Based on Opal Matrices in Accordance with the Data of Small Angle X-Ray and Neutron Scattering: Opal Matrix. Part I

The structure of nanocomposites based on opal matrices with different types of filling of structural voids is investigated. It is shown that the order in which tetrahedral and octahedral voids in the opal matrix are filled with various substances affects the X-ray diffraction pattern in the small angle region. On the basis of neutron diffraction, small angle X-ray scattering, and transmission electron microscopy data, models are proposed for filling the voids. The structural parameters of ordered nanocomposites based on opal matrices of different compositions are determined.
