ELECTROOPTICAL SWITCHING PROPERTIES OF A POLYMER-DISPERSED FERROELECTRIC LIQUID-CRYSTAL DEVICE

A fast and high-contrast polymer dispersed ferroelectric liquid crysta l (PDFLC) device was fabricated using a polymerization-induced phase s eparation technique which involves ultraviolet photopolymerization wit h an argon ion laser. The PDFLC film was oriented by the mechanical sh ear flow during the polymerization of an ultraviolet-curable adhesive. The switching times, contrast ratio and spontaneous polarization of t he PDFLC film were investigated. The sample preparation parameters, su ch as the curing time and curing intensity were also reported.
