Description
Summary:The droplet‐like morphology, typical for many polymer‐small‐organic‐molecule blends processed by spin coating, is quantitatively analyzed by gracing incidence small angle X‐ray scattering by Giuseppe Portale and co‐workers in article number 1702516. Using a combination of simultaneous X‐ray scattering, laser scattering, and laser interferometry measurements, a formation mechanism based on liquid‐liquid demixing followed by solvent partitioning is observed during spin coating.
