PREPOLYMER COMPOSITION FOR A POLYMER DISPERSED LIQUID CRYSTAL USING OLIGOMER AND PDLC FORMED BY USING THE SAME

摘要

PURPOSE: A prepolymer composition for polymer dispersed liquid crystal is provided to provide a polymer-dispersed liquid crystal composite film with sufficiently low driving voltage and excellent contraction ratio. CONSTITUTION: A prepolymer composition for polymer dispersed liquid crystal, using oligomers comprises 0.1-20 wt% of a polyfunctional oligomer, 0.1-99 wt% of a diluting agent, 0.1-99 wt% of a crosslinking agent, and 0.1-99 wt% of a photoinitiator. The composition ratio of the diluting agent and the crosslinking agent is 30:1-99:1. The polyfunctional oligomer is a urethane-based acrylate derivative compound containing an aliphatic silane. The diluting agent is tetrahydrofurfuryl methacrylate. The crosslinking agent is tripropylene glycol diacrylate or dipropylene glycol diacrylate. The photoinitiator is IRGACURE 2022.
