Anisotropic Diffusion and Phase Behavior of Cellulose Nanocrystal Suspensions

Structure and transformation of tactoids in cellulose nanocrystal suspensions

Cellulose nanocrystals obtained from natural sources are of great interest for many applications. In water, cellulose nanocrystals form a liquid crystalline phase whose hierarchical structure is retained in solid films after drying. Although tactoids, one of the most primitive components of liquid crystals, are thought to have a significant role in the evolution of this phase, they have evaded ...

Chiral Nematic Structure of Cellulose Nanocrystal Suspensions and Films; Polarized Light and Atomic Force Microscopy

Cellulosic liquid crystalline solutions and suspensions form chiral nematic phases that show a rich variety of optical textures in the liquid crystalline state. These ordered structures may be preserved in solid films prepared by evaporation of solvent or suspending medium. Film formation from aqueous suspensions of cellulose nanocrystals (CNC) was investigated by polarized light microscopy, op...

Light transport and rotational diffusion in optically anisotropic colloidal suspensions

2 Magnetic and optical properties of liquid crystalline colloidal particles 33 2. Introduction This work is concerned with the solution of an important problem of influence of a magnetic field on rotational diffusion in anisotropic colloidal solutions. It describes the results of experimental investigations of the author carried out using the method of diffusing-wave spectroscopy and the method...
