Controllable synthesis of raspberry-like PS–SiO2 nanocomposite particles via Pickering emulsion polymerization

Tuning Amphiphilicity of Particles for Controllable Pickering Emulsion

Pickering emulsions with the use of particles as emulsifiers have been extensively used in scientific research and industrial production due to their edge in biocompatibility and stability compared with traditional emulsions. The control over Pickering emulsion stability and type plays a significant role in these applications. Among the present methods to build controllable Pickering emulsions,...

The One-Step Pickering Emulsion Polymerization Route for Synthesizing Organic-Inorganic Nanocomposite Particles

Polystyrene-silica core-shell nanocomposite particles are successfully prepared via one-step Pickering emulsion polymerization. Possible mechanisms of Pickering emulsion polymerization are addressed in the synthesis of polystyrene-silica nanocomposite particles using 2,2-azobis(2-methyl-N-(2-hydroxyethyl)propionamide (VA-086) and potassium persulfate (KPS) as the initiator. Motivated by potenti...

Silica/Polyethylene Nanocomposite Particles from Catalytic Emulsion Polymerization

Catalytic emulsion polymerization of ethylene with nickel catalysts in the presence of silica nanoparticles affords stable dispersions of silica/polyethylene nanocomposite particles. The modification of the surface of silica particles by grafting upon their surface of octenylor octylsilanes is a prerequisite for obtaining composites. Different morphologies of composites particles were observed ...

Synthesis of Silica/Polystyrene Nanocomposite Particles by Miniemulsion Polymerization

Miniemulsion polymerization is one of heterogeneous polymerization method that can be effectively used to synthesis of various novel organic-inorganic nanocomposite particles. This method can provide opportunity of good incorporation between the polymer and inorganic phases in the formed submicrometer-sized particles. In this article, we report preparation polystyrene/silica nanocomposite p...
