Properties of Liquid Crystalline Polymer Film.

Thermotropic Liquid Crystalline Polymer Fibers

Super-strength, lightweight materials used in bullet-proof vests, high-performance cables and tires, and stealth airplanes are built from liquid crystalline polymer (LCP) bers. The remarkable strength properties are dominated by molecular alignment achieved as a result of the complex interactions at play in ber processes. The ber manufacturing process begins with a high temperature liquid phase...

SRG Inscription in Supramolecular Liquid Crystalline Polymer Film: Replacement of Mesogens

The photoinduced surface relief formation via mass transfer upon irradiation with patterned light has long been a subject of extensive investigation. In azobenzene-containing liquid crystalline materials, UV light irradiation that generates the cis isomer leads to the liquid crystal to isotropic photochemical transition. Due to this phase change, efficiency of the mass transfer to generate a su...

Surface anchoring on liquid crystalline polymer brushes

We present a Monte Carlo study of the surface anchoring of a nematic fluid on swollen layers of grafted liquid crystalline chain molecules. The liquid crystalline particles are modeled by soft repulsive ellipsoids, and the chains are made of the same particles. An appropriately modified version of the configurational bias Monte Carlo algorithm is introduced, which removes and redistributes chai...

Mechanical properties of in situ composites based on polycarbonate and a liquid crystalline polymer

The mechanical properties of in situ composites based on blends of polycarbonate and a liquid crystalline copoly(ester amide) (Vectra B950) have been studied as functions of the liquid crystalline polymer (LCP) concentration and the draw ratio, a processing parameter. It is shown that both the elastic modulus and the tensile strength of the in situ composites increase steadily with the LCP conc...
