Optical textures and orientational structures in cholesteric droplets with conical boundary conditions
AP Gardymova, MN Krakhalev, VY Zyryanov - Molecules, 2020 - mdpi.com
Cholesteric droplets dispersed in polymer with conical boundary conditions have been
studied. The director configurations are identified by the polarising microscopy technique.
The axisymmetric twisted axial-bipolar configuration with the surface circular defect at the
droplet's equator is formed at the relative chirality parameter N 0≤ 2.9. The intermediate
director configuration with the deformed circular defect is realised at 2.9< N 0< 3.95, and the
layer-like structure with the twisted surface defect loop is observed at N 0≥ 3.95. The …
