Contrast Variation Experiments for Probing the Structure of Pickering Nanoemulsion Oil Droplets Stabilized by Block Copolymer Nanoparticles

Abstract: Polymerisation-induced self-assembly is an efficient and versatile method of producing functional block copolymer spheres, worms and vesicles in a range of media (e.g. water, polar solvents or non-polar solvents). Recently, we have shown that these block copolymer nanoparticles can behave as model Pickering emulsifiers for both macro- and nanoemulsions. We wish to conduct contrast variation experiments in order to probe the structure of the adsorbed nanoparticles layer. In these experiments, the scattering length density of the oil phase will be contrast-matched to that of the aqueous phase. More specifically, these experiments will allow us to validate contradicting to each other electron microscopy and X-ray scattering results and determine insitu the structure of stabilizing layer adsorbed to the oil droplets which provide fundamental insights into mechanism of the emulsion formation.
