Study of Liquid Crystal Composite Films Prepared by Langmuir Blodgett Technique

Abstract

We have prepared homogenous Langmuir-Blodgett (LB) films of liquid crystals (LC) and it’s composite with nano-particles. Interaction between nano-particles and host LC matrix resulted in phase changes of monolayer. Orientation and ordering of LC at air-water interface have been significantly improved by adding nano-particles into it. It has improved many physical properties of liquid crystal matrix. These LB films have opened up opportunities for understanding of many properties for application point of view.
