AI Article Synopsis
- PDLC films were created using UV light to polymerize monomers mixed with liquid crystals and chiral dopants, focusing on the effects of these additives on the films' electro-optical properties.
- The introduction of the chiral dopant S811 resulted in lower initial light transmittance for the films, indicating that it affected their optical behavior.
- By varying the amounts of thiol and acrylate monomers, researchers found that adding a specific curing agent (Capcure 3-800) improved the films' performance, leading to reduced voltage requirements and better contrast in visual output.
Article Abstract
Polymer-dispersed liquid crystal (PDLC) films were prepared by the ultraviolet-light-induced polymerization of photopolymerizable monomers in nematic liquid crystal/chiral dopant/thiol-acrylate reaction monomer composites. The effects of the chiral dopant and crosslinking agents on the electro-optical properties of the PDLC films were systematically investigate. While added the chiral dopant S811 into the PDLC films, the initial off-state transmittance of the films was decreased. It was found that the weight ratio among acrylate monomers, thiol monomer PETMP and the polymercaptan Capcure 3-800 showed great influence on the properties of the fabricated PDLC films because of the existence of competition between thiol-acrylate reaction and acrylate monomer polymerization reaction. While adding polymercaptans curing agent Capcure 3-800 with appropriate concentration into the PDLC system, lower driven voltage and higher contrast ratio were achieved. This made the polymer network and electro-optical properties of the PDLC films easily tunable by the introduction of the thiol monomers.
