Abstract
The electro-optic performance characteristics of PDLC films using two different polymers, namely, poly (methyl methacrylate) (PMMA) and poly (vinyl chloride:vinyl acetate 17%) (PVC:VAC-17) and liquid crystal mixture E-8 (BDH, England) have been studied. It is found that the PMMA-based PDLC films have more superior mechanical and electro-optical properties than the PVC:VAC-17-based PDLC films. The performance characteristics of PDLC films, in general, improve significantly with increasing temperature. An optimum weight fraction of liquid crystal mixture is to be added in the polymer for good performance of the PDLC films. The finite solubility of liquid crystal mixture in the polymer affects the properties of the polymer matrix and hence the electro-optic performance characteristics significantly.
