title: Fabrication of polymer-silica core-shell particles using copolymeric spheres prepared via precipitation polymerization.
abstract: Silica-coated polymeric particles were synthesized based on cationic colloidal particles which were prepared by precipitation polymerization of divinylbenzene in the presence of a cationic monomer, N-[3-(dimethylamino)propyl]methacrylamide. Negatively charged silica precursors were interacted with the cationic charged dimethylamine groups in colloidal particles. The resulting polymer/silica core/shell particles were characterized by scanning electron microscopy (SEM). Moreover, omniphobic particles were achieved by coupling reaction of the core/shell particles with nonafluorohexyl-triethoxysilane. Their water/oil static contact angles were investigated.
