    Figures & Tables(7)
    Image of silver nanowires under the scanning electron microscope, their shape is as thin filaments with a length of approximately 6~8 μm.
    Schematic diagram of dual channel display scheme for optical orientation illumination. Two glass substrates correspond to different mask patterns, and are illuminated by rotating counter-clockwise by 22.5° and clockwise by 22.5°, respectively, with the center normal as the axis.
    Physical display of double images. The two patterns are “Panda” and “DHU”, respectively. (a), (b), (c)and (d) are the imaging effects when the directions of the polarizer and the polarizer are 0°, 45°, 90° and 135°, respectively.
    (a) Diagram of the liquid crystal polymer film stripped from the glass substrate and placed on the flexible substrate; (b) Physical display of the liquid crystal flexible display trademark encapsulated by the polarizer and transparent PVC soft film.
    Comparison of display effect of LC films under different thicknesses of 10~100 μm. (a) 10 μm; (b) 30 μm; (c) 60 μm; (d) 100 μm.
    (a) Picture and operation interface of dynamic mechanical analyzer DMA850 of TA company, USA; (b) Photo of fixation of the experimental sample on the instrument measuring fixture.
    Stress-strain curves of liquid crystal thin films doped with different concentrations of silver nanowires (AgNWs)
