Stripe‐Like Pattern Formation in Airbrush‐Spray Deposition of Colloidal Polymer Film

Abstract

Abstract We use the versatile technique of Grazing incidence small angle X‐ray scattering (GISAXS) to investigate the ordering of colloidal polymer films deposited on Silicon substrate by airbrush‐spray coating. A lateral ordering of the polymer colloids is highly desirable as it would open a promising route to generate laterally structured templates and scaffold for the fabrication of ultra‐high density media. The study shows a strong dependency of the film homogeneity on the number of spray cycles and a strong influence of the solvent choice on the film lateral ordering.
