Formation of Composite Polymer Photonic Crystals and Study of Their Properties by Optical Spectroscopy Methods

Monodisperse polymer particles of the core–shell type were produced using sequential emulsion and seed emulsion polymerization methods. The structure of the surface layer of the particles was studied using scanning electron microscopy. It has been established that sequential emulsion polymerization makes it possible to obtain particles with the lowest dispersity values of their diameter. The introduction of methyl methacrylate both at the stage of core synthesis and during the formation of the shell leads to the formation of spherical particles with a smooth surface layer. Based on such particles, films with pronounced properties of photonic crystals were obtained, and their Bragg reflection spectra in polarized light were studied.
