Characterization of thermotropic liquid crystalline polymers

The characterization of thermotropic, main chain liquid crystalline polymers for the type, thermal and thermodynamic properties, order, and degree of liquid crystallinity of the anisotropic phase is described through the use of the following methods: (1) polarized light microscopy, (2) wide angle X—ray diffraction, (3) differential scanning calorimetry, (4) small angle light scattering, (5) ele...

Thermotropic Chiral Nematic Side-chain Polymers

LLE Review, Volume 66 103 Low-Molar-Mass Liquid Crystals Liquid crystals (LC’s) represent a state-of-matter intermediate between a solid crystal and an isotropic liquid. A liquid crystal flows like an ordinary liquid, while other properties, such as optical and dielectric anisotropies, resemble those of a crystalline solid.1 In general, a somewhat rigid and anisomeric molecular shape (e.g., cyl...

Molecular organization in side chain liquid crystalline polymers

2014 We have synthesized a series of side chain liquid crystalline polymers which differ only by the terminal end group of the mesogenic moieties. X-ray diffraction experiments show the existence of a lower temperature smectic A phase following the nematic phase, while optical microscopy was not able to show smectic A characteristic textures. The diffraction patterns give information about the ...

Novel biaxial nematic phases of side-chain liquid crystalline polymers.

We present a mean field theory to describe biaxial nematic phases of side-chain liquid crystalline polymers, in which rigid side-chains (mesogens) and rigid-backbone chains favor mutually perpendicular orientations. Taking into account both excluded volume and attractive interactions between rigid rods, novel biaxial nematic phases are theoretically predicted. We calculate uniaxial and biaxial ...
