Homeotropic-planar orientation mode patterning via inkjet printing. (a) Scheme of inkjet printing onto a phenyl benzoate (PPBz) thin film. (b) Photoaligned PPBz films in printed regions, commanded by a surface skin layer of poly(butyl methacrylate) (PBMA)-b-PAz and linearly polarized light (LPL) irradiation for 1-mm (left) and 5-mm (right) wide lines. (c) The appearance and disappearance of a birefringence patterning observed by polarized optical microscopic (POM) under crossed polarizers. The emergence of the image is fully switched by rotating the polarizers at 45°. Adapted with permission.128 Copyright 2014, Nature Publishing Group.
