Polymer ellipsoids are typically accessible through a two-step fabrication procedure, involving the synthesis of spherical particles followed by thermal stretching, a time-consuming and complicated process. In this study, a straightforward method is presented for preparing polymer ellipsoids via emulsion polymerization, utilizing the jamming of nanoparticle surfactants at the oil-water interface and the membrane emulsification technique. The size and shape of polymer ellipsoids can be precisely controlled by adjusting the interfacial activity of nanoparticle surfactants and emulsification parameters. This approach provides a scalable and cost-effective pathway for the production of polymer ellipsoids, with potential applications across various fields.
