From: New strategies and implications for the photoalignment of liquid crystalline polymers
Schematic illustrations, grazing incidence angle X-ray scattering (GI-SAXS), atomic force microscopic (AFM) and transmission electron microscopic (TEM) data for a series of in-plane photoalignments of PS-b-PAz films via surface segregation of poly(butyl methacrylate) (PBMA)-b-PAz. (a) PS-b-PAz film without the addition of PBMA-b-PAz. (b) PS-b-PAz film obtained by the addition of 10 weight % of PBMA-b-PAz and annealing (case f in Figure 4). (c) Photoaligned PBMA-b-PAz obtained by linearly polarized light (LPL) irradiation. For explanations of the GI-SAXS, AFM and TEM data, see the text.
