| Outline of Final Research Achievements |
The modification of the physical properties of liquid crystals by doping nanoparticles have received much attention from the view point of the enhancement of the performance of LCDs. Reflecting these trends several research groups reported on heterogeneous liquid crystal suspensions using; fullerene, noble metal nanoparticles, and semiconductor nanoparticles.
Poly(γ-cyclodextrin) (P γCyD)-protected ZrO2 nanoparticles were prepared by using a microwave reactor equipped with ultrasonic nozzle mixing a tetraethylene glycol solution of zirconium ethoxide in the presence of poly(γ -cyclodextrin). The response time of this twisted nematic liquid crystal devices (TN-LCDs)in the presence of P γ CyD-ZrO2 nanoparticles was faster than that in the absence. The threshold voltage of TN-LCDs by doping P γ CyD-ZrO2 nanoparticles decreased. The decrease of threshold voltage can reduce power consumption, which may meet the demands of future power-saving LCDs.
