title: Preparation of nanocapsules containing the two-phase core materials.
abstract: In this study, copolymer nanocapsules containing the two-phase core materials were prepared by mini-emulsion polymerization using styrene (St) and methylmethacrylate (MMA) as comonomer, in which the ZnO nanoparticles organic suspension was prepared by solvothermal synthesis method. The obtained materials were characterized by dynamic light scattering (DLS), transmission electron microscopy (TEM), atomic force microscopy (AFM), UV-visible spectrophotometry and fluorescence spectrometer. The particle size of the prepared ZnO nanoparticles dispersed in the organic solvent was less than 20 nm. The resulting polymer nanocapsules have 100-200 nm in diameter and approximately 10-20 nm in the wall thickness. The surface of the polymer nanocapsules is smooth and clear.
