Effect of oligomeric photoinitiator on the preperation and electro-optical property of polymer-dispersed liquid crystal

摘要

Effects of such factors as polymerization temperature and a newly synthesized oligomeric photoinitiator (PEDI380) on the electro-optic characteristics of polymer/LC composite films prepared by the UV-curing method were investigated. The polymer-dispersed liquid crystal cells were made with oligomeric photoinitiator PEDI380 by UV-curing method exhibited both low driving voltage (V_(90)) and high contrast ratio under optimum formulation condition.
