From: Robust icephobic coating based on the spiky fluorinated Al2O3 particles

SEM image of the omniphobic, icephobic surface is supplied. (A) Scale bar is 10 μm. (B) Scale bar is 4 μm. (C) Scale bar is 1 μm. The very similar topographies were registered for the surfaces obtained with the dip—coating and spraying methods.
