The schematic diagrams of the proposed RM-coated system. (a) Isotropically aligned polymer chains before rubbing, (b) polymer chains aligned with rubbing direction after rubbing (the arrow indicates the azimuthal direction defined by the rubbing process.), (c) spin-coated RM molecules aligned in the rubbing direction, (d) RMs polymerized by UV exposure, (e) LC alignment on the polymerized RM layer, and (f) the angular dependence of optical anisotropy of rubbed PI film (open circles) and RM-coated PI film (open triangles).
Surface anchoring energies with rubbing times. (Solid lines and dashed lines represent azimuthal anchoring energy and polar anchoring energy, respectively.)
(a) FTIR spectra of rubbed PI film (solid line) and RM-coated PI film (dashed line), (b) polarization angle dependence of IR absorption of rubbed PI film (solid line with open circles) and RM-coated PI film (dashed line with open triangles) at 1490 cm−1: curves are fitted using a Gaussian function.
The contact angle characteristics of water (open circles) and NLC (open triangles) with different RM concentrations.
The relaxation time characteristics of the conventional (empty symbols) and RM-coated (crossed symbols) cells. (Circle symbols and square symbols represent TN and FFS cells, respectively.)
