PA05 Thickness Dependence on Viscoelasticity of Liquid Crystal Thin Film on a Solid Surface

Abstract

It has been reported that a solid-like interfacial layer can be formed between polymer sublayers and liquid crystals. In the present study, the thickness dependence of viscoelasticity of liquid crystal thin film was investigated using a quartz crystal microbalance (QCM). The results indicate that thin liquid crystal film of 23 nm thick or thinner exhibited solid-like characteristics without liquid crystalline properties.
