Synthesis and properties of siloxane modified perylene bisimide discotic liquid crystals
A series of symmetric and asymmetric 1,6,7,12-tetrachloroperylene bisimides (PBICls) were synthesized and modified by siloxane substituents at the imide nitrogen atom. Siloxane substitutions do not apparently affect the electronic properties of PBICIs as demonstrated by CV experiments. They display both thermotropic and lyotropic liquid crystalline behaviors. The effect of differe...

Dependence of critical condition in liquid chromatography on the pore size of column substrates
The dependence of critical condition in liquid chromatography on the pore size of column substrates was investigated by Lattice Monte Carlo simulations. In the current study, the pore was modeled by a square channel and polymer chains were modeled by both the random walk (RW) and the self-avoiding walk (SAW) models. When the polymer chains were modeled by the RW model, the critical conditions in t...

Crystallization behaviors of poly(ethylene 2,6-naphthalate) in the presence of liquid crystalline polymer
The crystallization behaviors and morphology of poly(ethylene 2,6-naphthalate) (PEN) in the presence of liquid crystalline polymer (LCP) Vectra RD501 have been studied by differential scanning calorimetry (DSC), polarized optical microscopy (POM), atomic force microscopy (AFM), and wide-angle X-ray diffraction (WAXD). It was found that the LCP in PEN/LCP blends accelerates the crystallization ...

Cellulose-based solid-solid phase change materials synthesized in ionic liquid
A series of cellulose graft poly(ethylene glycol) (cellulose-graft-PEG) copolymers as phase change materials (PCMs) were synthesized in ionic liquid by using 4, 4-diphenylmethane diisocyanate as coupling reagent. FTIR and H-1 NMR characterized the structure of the copolymers. Differential scanning calorimetry (DSC) indicated that the copolymers showed phase transitions with large thermal stor...

31. Experimental study of dynamics of topological defects in nematic polymer liquid crystals
The dynamics of stringlike defects and the shrinkage and annihilation processes of individual defect loops in a nematic polymer liquid crystal have been experimentally investigated. In 40<t<500?s, the line density of defects ρ scales as ρ(t) ∼ t−1, as expected by theory and as found in the experimental studies of some low molecular weight (LMW) liquid crystals. For indi...

28. Application of topological theorems to studies of coalescence and ordering processes in liquid crystal droplets
We have observed the coalescence process of elementary nematic droplets having either radial or bipolar structure. The coalescence causes symmetry-breaking in elementary droplets and then creates new defects either in the bulk or at the surface of the coalesced droplet; the defects annihilate and the shape of the droplets after coalescence changes, resulting in symmetry-recovering and formati...
