Surface Encapsulation of Nano-CaCO3 Particle by In Situ Emulsion Polymerization
The nano-CaCO3/polyacrylate core-shell inorganic-organic complex nano-particles were prepared by in situ emulsion polymerization based on fresh slush pulp of calcium carbonate (CaCO3) nanoparticles in this paper. The dispersion and encapsulation of nanoparticles were investigated by transmission electron microscopy (TEM) and electron spectroscopy for chemical analysis(ESCA). The results showed that in the presence of nano-CaCO3 particles, the in situ emulsion polymerization of acrylates was carried out smoothly, and polyacrylates successfully encapsulated on the surface of nano-CaCO3.
