CHARACTERIZATIONS OF LIQUID-CRYSTAL ALIGNMENT ON POLY-DIISOPROPYL FUMARATE LANGMUIR-BLODGETT-FILMS

We have fabricated Langmuir-Blodgett (LB) films of a poly-diisopropyl fumarate (PDiPF) for nematic liquid crystal alignment and have charact erized their alignment capability using a nematic liquid crystal of pe ntyl-cyano biphenyl (5CB). We prove that the PDiPF-LB films can be obt ained by simple processes compared with polyimide-LB films. We present deposition conditions of the PDIPF-LB films, and the relationship bet ween optical axes of the PDiPF-LB films and the alignment direction of 5CB on the films.
