It is very important to know the orientation mechanism of liquid crystal molecules on solid surfaces. The orientation of thin liquid crystal films confined between two solid surfaces becomes more pronounced than that of bulk liquid crystals. Therefore liquid crystals show different properties in the nanospace from those in the bulk. Their orientation is affected by interactions between solid surfaces and liquid crystals and/or between liquid crystals, but the details are not known. To investigate properties of thin liquid crystal films in confined dimensions, we developed the novel system simultaneously determines the shear and surface force as a function of the surface separation. The resonance method was used for the shear measurement. By using this method, we studied the behaviors of liquid crystals (6CB) oriented parallel or perpendicular to substrate surfaces.
