A strategy to the batch-scale fabrication of anisotropic particles with diverse morphologies and various chemical compositions is reported by applying the highly structured fluids of Cerberus emulsions as templates. The Cerberus emulsions are produced simply by traditional one-step vortex mixing the...

520 |a A strategy to the batch-scale fabrication of anisotropic particles with diverse morphologies and various chemical compositions is reported by applying the highly structured fluids of Cerberus emulsions as templates. The Cerberus emulsions are produced simply by traditional one-step vortex mixing the surfactant aqueous solution with three immiscible oils which are selectively photocurable or incurable. Anisotropic particles are subsequently fabricated by UV-induced polymerization. The diversity in the morphology of the particles is provided by the various controllable geometries of the Cerberus droplets. Various droplet morphologies of "engulfed-linear", "partial-engulfed-linear", and "linear-singlet" are obtained by employing various oil combinations. Precise control of the volume fraction of each segment within the droplet is realized on the basis of the three-phase diagram of the oils. The wide size range is achieved from hundreds of micrometers continuously down to nanometers, with topology remaining. In addition, for a matrix droplet with a fixed morphology, the multiplicity in the chemical composition and in the geometry of the resultant anisotropic particles is realized by selectively polymerizing one, two, or three of the oil lobes. Morphologies of "crescent moon", "etched-Janus", and "sandwich-Janus" are obtained with homogeneous or multiple distinct chemical compositions. The reported strategy is universal and can be extended to a huge family of polymeric anisotropic particles
