Structures and Alignment of Anisotropic liquid crystal particles using microfluidics |
| 초록 |
Anisotropic porous liquid crystal (LC) particles with ~ 60 m diameters were prepared using microfluidics and directional UV photopolymerization at room temperature in the presence of a magnetic field. RM257 and 5CB in the RM257/5CB mixtures were reactive mesogen and orientation-inducible LC porogen, respectively. The RM257/5CB droplets coated with sodium dodecyl sulfate (SDS) and poly(vinyl alcohol) (PVA) With magnetic field highly anisotropic LC particles were produced whereas in the absence of a magnetic field helical structures were formed. The detailed internal orientation in the anisotropic LC particles was studied using more than 240 two-dimensional micro-beam X-ray diffraction patterns per particle, which provided the detailed orientation director field in the particle. The combination of the porous structure and alignment of the LC chains in the anisotropic LC particles exhibited this unique rotating ability in the LC cell. |
