Figure 2. (A-D) GIWAXS characterization of thin-film samples processed with a single-solvent system at speeds of 0.3, 0.9, 1.8 and 3.0 mm/s; (E-H) GIWAXS characterization of thin-film samples processed with a dual-solvent system at speeds of 0.3, 0.9, 1.8 and 3.0 mm/s; (I-L) GIWAXS diffraction signal intensity diagrams for blade-coating rates of 0.3, 0.9, 1.8 and 3.0 mm/s along the out-of-plane direction; (M) Schematic illustration of the single-solvent scraping process; (N) Schematic illustration of the dual-solvent scraping process. GIWAXS: Grazing incidence wide-angle X-ray scattering.
