Self-cleaning behavior in polyurethane/silica coatings via formation of a hierarchical packed morphology of nanoparticles

•Self-cleaning behavior was imparted to the hydrophilic polyurethane.•A hierarchical packed morphology is responsible for the superhydrophobicity.•Prolonged pressing process cannot lead to superhydrophobicity due to migration of TPU.•Samples exhibited excellent stability against media with a wide ra...
