Self‐Assembled Magnetic Control Lever Embedded in Photonic Liquid Crystalline Microcapsule

Abstract

The behavior of water/oil/water double emulsion droplets with a cholesteric liquid crystalline middle phase (photonic microcapsules, PMCs) with magnetic nanoparticles (m-PMCs) in a uniform magnetic field is demonstrated. The needle-like aggregate of magnetic nanoparticles forms along the disclination line by the elastic interaction between particles and liquid crystalline director field. The m-PMC reorients in a uniform magnetic field.
