Abstract

We investigated the effect of concentration on the electro-optical properties of some flexible PDLC formulations with various liquid crystal mixtures. The PDLC films were prepared on flexible ITO-PET supports by UV-PIPS phase separation method and the uniform film thickness was insured by plastic micro-spacers. We found that depending on the type of liquid crystal and PDLC process conditions, the electro-optical properties (off-state and onstate transmissions, switching voltages and response times) provide different concentration dependency with various trends in the studied flexible PDLC formulations
