Anisotropic Spreading of Liquid Crystals and Isotropic Fluids on Anisometric Surface of DVD Discs

The first experimental data on spreading of liquid crystal droplets over the surface with a regular submicron relief are presented. It is established that such relief produces a motion of a precursor film in the direction of grooves. The dynamics of motion of a precursor film and a contact line is i...

Description
Summary:The first experimental data on spreading of liquid crystal droplets over the surface with a regular submicron relief are presented. It is established that such relief produces a motion of a precursor film in the direction of grooves. The dynamics of motion of a precursor film and a contact line is investigated via polarizing microscopy. The possible influence of anisotropic near-surface viscosity on spreading of liquid crystal droplets is discussed.
