PREPOLYMER COMPOSITION FOR POLYMER DISPERSED LIQUID CRYSTAL COMPOSITE MEMBRANE WITH IMPROVED ADHESIVE FORCE AND THE POLYMER DISPERSED LIQUID CRYSTAL COMPOSITE MEMBRANE PREPARED THEREBY

摘要

PURPOSE: A prepolymer composition is provided to prepare a polymer dispersed liquid crystal composite membrane with excellent adhesive force after UV curing compared with a conventional polymer dispersed liquid crystal composite membrane, using diluent with excellent adhesive force.;CONSTITUTION: A prepolymer composition for a polymer dispersed liquid crystal composite membrane comprises 0.1-20 parts by weight of multifunctional oligomer, 0.1-99 parts by weight of diluent and 0.1-99 parts by weight of cross-linking agent. The prepolymer composition further includes 0.1-99 parts by weight of photoinitiator. The diluent and cross-linking agent have a composition ratio of 30:1-99:1. The multifunctional oligomer is an urethane-based acrylate derivative compound in which hydroxyethylacrylate is attached to a terminal. The cross-linking agent is one or more selected from trimethylpropane triacrylate and polyethylene glycol diacrylate.;COPYRIGHT KIPO 2011
