In this paper, a kind of photo-alignment materials of liquid crystal with nano-structured is introduced. The samples differ in optical anisotropy, which are subjected to different pre-bake temperatures and different exposure energy. The optical anisotropy are predicted by Secondary fitting analysis. The rationality of the fitting equation was verified by AFM test on the material surface.
The microwave phase modulation of liquid crystal depends on the rotation angle of liquid crystal molecules under the external electric field, and the alignment layer on the surface of liquid crystal drive electrode important influence on it. In this paper, the microwave phase modulation characteristics of non-chiral doped nematic liquid crystal under different materials with polar alignment layer and different rubbing alignment conditions are studied. The variation of different frictional strengths and microwave phase-shifts magnitude with the driving voltage of liquid crystal was tested through the test method. It provides a basis for the design of a liquid crystal microwave modulator and the selection of liquid crystal alignment materials.
