From: New strategies and implications for the photoalignment of liquid crystalline polymers
Schematic illustrations and grazing incidence angle X-ray scattering (GI-SAXS) data for a series of in-plane photoalignments of phenyl benzoate (PPBz) films via surface segregation of poly(butyl methacrylate) (PBMA)-b-PAz. (a) PPBz film without the addition of PBMA-b-PAz. (b) Random planar alignment of the PPBz film obtained by the addition of 3 weight % of PBMA-b-PAz and subsequent annealing (case f in Figure 4). (c) Homogeneous photoalignment of the film in b after linearly polarized light (LPL) irradiation. For explanations of the GI-SAXS analysis, see the text.
