The main objective of this work was to control and manipulate tuneable equilibrium structures in elastomeric spherical particles. The cross-linked urethane/urea polymeric spheres with two soft segments, polypropylene oxide and polybutadiene, were prepared by reacting a poly(propyleneoxide)-based triisocyanate-terminated prepolymer (PU) with poly(butadienediol) (PBDO), with different weight ratio. Wrinkling on elastomeric Janus spheres is induced by UV irradiation and permanently imprinted by swelling the particles in an appropriate solvent, followed by drying. The surface tailoring of the Janus elastomeric spheres, found by SEM, is dependent on the PU/PBDO ratio and on the elastic properties of the particles.
