Abstract

original image

We demonstrate the use of a microfluidic setup to prepare monodisperse and spherical beads from a liquid crystalline elastomer. These particles show a strong and reversible shape change into a cigar-like conformation during the transition into the isotropic phase. These properies are a result of the monodomainic alignment of the mesogens in the flow field of the microfluidic setup.
