The interface adsorption behavior in a Pickering emulsion stabilized by cylindrical polystyrene particles

[Display omitted] In this study, cylindrical polystyrene particles were applied as a particulate stabilizer to prepare a Pickering emulsion of decane (oil)/water. Unlike the spherical particles that are typically used in Pickering emulsions, the cylindrical particles enhanced the emulsion’s stability (up to 1 year). Furthermore, the cylindrical particulate stabilizer enabled a stable emulsion across a wide range of pH. Notably, unique adsorption behavior of the cylindrical particles on an oil droplet was observed, in which the cylindrical particles connected head to head to form a network that acted as a cage around the oil droplet.
