چکیده

Size fractionation, amplified by the surface charge density of graphene oxide (GO) sheets, broadens the pH dependent isotropic (I) to nematic (N) phase transition in aqueous dispersions of graphene oxide (GO). In this biphasic region, a highly organized droplet nematic phase of uniform size (20 ± 2.8 μm diameter) with an isotropic interior is observed.

Sharp-interface nematic-isotropic phase transitions with flow

We present a sharp-interface theory for phase transformations between the isotropic and uniaxial nematic phases of a flowing liquid crystal. These equations include a supplemental interface condition which expresses the balance of configurational momentum. As an application, we study the behavior a spherical isotropic drop surrounded by a radially-oriented nematic phase. For this problem, the b...

Dielectric spectroscopy of isotropic liquids and liquid crystal phases with dispersed graphene oxide

Graphene oxide (GO) flakes of different sizes were prepared and dispersed in isotropic and nematic (anisotropic) fluid media. The dielectric relaxation behaviour of GO-dispersions was examined for a wide temperature (25-60 (o)C) and frequency range (100 Hz-2 MHz). The mixtures containing GO flakes exhibited varying dielectric relaxation processes, depending on the size of the flakes and the ela...

Highly Confined Phases of Graphene Oxide Sheets

The graphene oxide (GO) is widely used as a graphene precursor. It has been recently evidenced that this object can form different lyotropic liquid crystals phases observed in highly anisotropic colloids. The confinement of GO sheets, a two-dimensional (2D) crystal is herein aim of study. The binary GO water is studied to describe the liquid crystallinity of concentrated dispersions, characteri...

Temperature dependence of droplet breakup in 8CB and 5CB liquid crystals.

Droplet breakup of many Newtonian fluids is well described by current experiments, theory, and simulations. Breakup in complex fluids where interactions between mesoscopic structural features can affect the flows remains poorly understood and a burgeoning area of research. Here, we report on our investigations of droplet breakup in thermotropic liquid crystals. We investigate breakup in the sme...

Nematic-isotropic phase transition in a liquid-crystal droplet.

Possible phases in a nematic liquid crystal confined to a spherical submicrometer droplet embedded in a solid polymer are analyzed in terms of a Landau — de Gennes theory. For a droplet with a radial structure we show that the strength of the nematic-polymer interfacial interaction affects the nematic-paranematic (partially ordered isotropic phase) phase transition and may in addition induce a ...
