Abstract: | Three-dimensional periodic solid-state film structures with a face-centered cubic lattice and a high degree of perfection
have been prepared from monodisperse particles of styrene copolymers with methacrylic acid. It has been shown that these structures
can be successfully used not only as model objects for studying specific features of light propagation in photonic crystals
but also as templates for synthesizing inverse opal-like structures. The influence of the degree of hydrophilization of the
surface layer of polymer particles forming a polymer template and the template synthesis conditions on the quality of an inverse
opal-like TiO2-based structure has been analyzed. |
