제목 The morphology of Liquid Crystals on different surfaces
초록 Many liquid crystals have been studied to develop, in particular, displays and sensing devices. Progress in these applications depends on a good comprehension of the behavior of liquid crystals in different surfaces. At surfaces, liquid crystal molecules anchor in a particular orientation due to intermolecular interactions with the substrate molecules. Common configurations are ‘planar’ in which molecules align parallel to the substrate and ‘homeotropic’ in which molecules align perpendicular to the substrate. These conditions can be controlled by adsorbing hydrophilic or hydrophobic molecules onto the substrate, among other methods. we find special textures of liquid crystals on the different substrates. We have shown that liquid crystals have particular morphology by changing phobicity of the substrates which are flat, in the confined microchannel, and on the crystalline surfaces.
