碩士 === 國立彰化師範大學 === 光電科技研究所 === 94 === We investigated the electrooptical responses of the carbon nanotube doped liquid crystal cells. The cells were constructed in the twisted geometry and doped with various amount of carbon nanotubes. Experimental results revealed that the doped carbon nanotubes influence the dielectric anisotropy and elastic constant of the liquid crystal carbon nanotube mixture. The carbon nanotube dopant was found significantly improve electrooptical responses of the liquid crystal cell. Additionally, the dc measurement indicates that the hysteresis in the transmission versus applied dc voltage curve of the cell is reduced when CNTs are doped into the LC mixture.
