Nanostructured Relief for Homeotropic Orientation of Liquid Crystal Molecules and Its Possible Studying by Different Methods

Abstract
In this paper the features of the nanostructured homeotropic relief at the interface between solid substrate coated with conducting layer and electrooptical liquid crystal layer are considered. The features of the relief are connected with the using of carbon nanotubes or graphene oxides. This relief is created by laser technique under condition of electric field orientation and following treatment with surface electromagnetic wave. The obtained homeotropic relief is studied by the methods of spectral analysis, scanning microscopy, as well as microhardness instrument and by the visualization of the equilibrium contact angle via video camera.
