Large-scale fabrication of polymer ellipsoids with controllable patches via the viscosity-induced deformation of spherical particles

Abstract

A simple and controllable strategy to synthesize polymer ellipsoids via the viscosity-induced deformation of spherical particles is proposed. These polymer ellipsoids can be employed as living seed particles to fabricate patchy ellipsoids with controlled protrusions. Most importantly, the methodology presented here will make a breakthrough in the preparation of ellipsoidal particles.
