Schematic representation of the preparation of Pickering nanoemulsions. (a) Synthesis of PGMA₄₈-PTFEMA₅₀ nanoparticles of 25 nm diameter via RAFT emulsion polymerization of TFEMA using a PGMA₄₈ steric stabilizer. (b) TEM image of the resulting PGMA₄₈-PTFEMA₅₀ nanoparticles. (c) Fluorescence micrograph of the initial Pickering macroemulsion produced when excess nanoparticles are homogenized with n-dodecane for 2.0 min at 15 500 rpm. (d) This precursor macroemulsion was then further processed using a commercial LV1 microfluidizer (Microfluidics Ltd., USA) to afford a Pickering nanoemulsion.
