CHAPTER 3: Polymer Colloidal Particles Prepared by Pickering Emulsion Polymerization or Self-Assembly Method

In recent years, because of their wide applications in the cosmetics, food and paint industries, studies of emulsions and colloidal particles stabilized by solid particles in the nanometre to micrometre-size range have attracted intense interest in the chemistry and material science community. In this chapter, emulsions and colloidal particles stabilized by clay layers with different polymer brushes, amphiphilic gold nanoparticles and Janus structures, are reviewed. The favourable interfacial energy reduction is achieved when the brush-modified particles are used in Pickering emulsions. The self-assembly of the solid particles at a liquid–liquid interface improves the stability of Pickering emulsions significantly, and colloids with solid particles on the surface were prepared by an emulsion polymerization method.
