Alignment of Liquid Crystals on Polyimide Films Exposed To Ultraviolet Light
The influence of unpolarized and linearly polarized UV exposure on previously rubbed as well untreated thin polyimide ͑PI͒ alignment layers was studied. Optical retardation and surface morphology measurements were carried out to understand the nature of surface modification as a function of the polarization and the exposure time of the UV light under different surface conditions. The exposure of ...
متن کاملModel of liquid crystal alignment by exposure to linearly polarized ultraviolet light.
A simple theoretical model of liquid crystal ͑LC͒ alignment by exposure to linearly polarized ultraviolet ͑UV͒ light is proposed. The model predicts a universal relationship describing the change of the LC anchoring direction with exposure times, and the changes of polarization direction for the case of a double linearly polarized UV exposure process. This relationship is quantitatively confirmed b...
متن کاملTuning the Mechanical Properties in Model Nanocomposites: Influence of the Polymer-Filler Interfacial Interactions
Photoalignment layers comprising Polymer 1 were prepared using linearly polarized UV-irradiation for chloroformvapor annealing of p-conjugated oligomer films, both processes conducted at room temperature. The resultant uniaxially oriented monodomain films exhibited S 1⁄4 0.74 (at Pr 1⁄4 0.90) and 0.82 (at Pr 1⁄4 0.95) in OF and OF2T films, respectively, apparently limited by film dewetting in c...
متن کاملElectrically driven director-rotation of swollen nematic elastomers as revealed by polarized Fourier transform infrared spectroscopy.
We have investigated the director reorientation behavior of unconstrained nematic gels (nematic elastomer swollen by low molecular mass liquid crystals) under electric fields by means of polarized Fourier transform infrared (FTIR) spectroscopy. The polarized FTIR reveals that the director rotates about the (y) axis normal to the original director ( x axis) and field directions ( z axis), and th...
متن کاملStructural ordering in F8T2 polyfluorene thin-film transistors
We have used thermal treatment and rubbed polyimide alignment layers to produce large domains of poly(9,9dioctylfluorene-co-bithiophene) alternating copolymer (F8T2). The direction of rubbing on the polyimide surface determines the orientation of these domains, allowing us to create thin-film transistors with channel lengths parallel and perpendicular to the liquid crystal polymer director. We ...
