(A) Schematic representation of the surfactant-free synthesis of colloidal nanocomposite particles by aqueous emulsion copolymerization; (B) schematic representation of the mechanism of formation of colloidal, stable poly(acrylate)/silica particles. Blue circles indicate silica particles; orange regions show polymer, and the 2,2’-azobis(2-methylpropionamide) dihydrochloride (AIBA) initiator is represented by red “+”.
