Functionalization of direct-emulsion disperse-phase surface by zinc oxide nanoparticles using layer-by-layer electrostatic assembly

Polyelectrolyte and nanocomposite (zinc oxide nanoparticles/polymer) coatings on the surface of a direct-emulsion disperse phase containing fluorescent dye were obtained using layer-by-layer electrostatic assembly. The volume fraction of inorganic nanoparticles was varied by changing the number of polymer layers in the coating. The loaded microcontainers were characterized by fluorescence confocal and scanning electron microscopy (SEM). The parameters influencing the quality characteristics of the images were found, and the optimal conditions for the preparation and study of such systems using SEM were selected. It was demonstrated that the ultrasonic treatment of microcontainers influences the degree of their aggregation and, in the case of nanocomposite coatings, results in a reduction of the microparticle size.
