Figure 13.
Optical micrographs and schematic illustrations of the configurations of LCs within LC droplets, shown as a function of LC droplet size (with constant surface chemistry). (A–D) Polarized light micrographs (crossed polarizers) of 5CB droplets hosted within polymer capsules with diameters of (A) 8.0 ± 0.2 μm, (B, C) 1.0 ± 0.2 μm, or (D) 0.70 ± 0.08 μm. (E–G) Schematic illustrations of bipolar (E), preradial (F) and radial configurations (G) of LCs, corresponding to the micrographs in A, B and C, and D, respectively. Scale bars are 2 μm in AC and 1 μm in D. Modified and reproduced with permission.16
