Superhydrophobic coating was fabricated by spraying the mixture of poly (methyl methacrylate) (PMMA) and hydrophobic silica nanoparticles (SNs) on steel surface. Anti-icing tests were carried out in two ways: freezing water (0 degrees C) dripping and condensation of atmospheric humidity in low temperature (-20 degrees C). In the water dripping test, no ice film could be observed compared with steel substrate, due to the bouncing behavior of water droplet; while in the condensing condition, the superior anti-icing behavior could be attributed to the overcooled water that formed on superhydrophobic coating. Besides, the prepared surface exhibited outstanding anti-corrosion character. (C) 2016 Elsevier B.V. All rights reserved.
