Liquid Crystal Alignment on Carbonaceous Surfaces with Orientational Order

We used near-edge x-ray absorption fine structure (NEXAFS) spectroscopy to link the orientational bond order at three carbonaceous surfaces-rubbed polyimide, ion beam-irradiated polyimide, and ion beam-irradiated diamond-like carbon films-with the direction of liquid crystal (LC) alignment on these...
