제목 Thin SWNTs/Conjugate Block Copolymer Nanocomposites for High Performance Liquid Crystal Alignment and Switching
초록 We developed a high performance liquid crystal (LC) alignment layer of ultra-thin single wall carbon nanotubes (SWNTs) and a conjugated block copolymer nanocomposite solution-processible for conventional twisted nematic (TN) LC cells. The alignment layer is based on non-destructive solution dispersion of nanotubes with poly(styrene-b-paraphenylene) (PS-b-PPP) copolymer and subsequent spin coating, followed by conventional rubbing without post-annealing process. LCs were well aligned with stable pre-tilt angle on our extremely transparent nanocomposite which gave rise to superfast switching of TN LC molecules. Furthermore, TN LCD cells containing our SWNTs nanocomposite alignment layers exhibit low power operation at effective switching voltage amplitude even without capacitance hysteresis.
