Abstract: C1.00094 : Effect of carbon nanotubes on the crystallization and ordering behavior of liquid crystals
Preview Abstract Abstract
We used carbon nanotubes (CNTs) to affect the crystallization behavior of smectic, cholesteric and nematic liquid crystals and of their blends at different compositions. Using polarized microscopy and microscopic transmission ellipsometry we observed significant change in the crystal structure and orientation. The carbon nanotubes served as nucleation centers for crystal growth. Differential Scanning Calorimetry results showed large shifts in the phase transition temperatures. This is due to the effect of the CNTs on the crystallization kinetics.
