Preparation and Anti-Icing Property of a Porous Superhydrophobic Magnesium Oxide Coating with Low Sliding Angle

Abstract

A porous superhydrophobic magnesium oxide coating with low sliding angle was prepared by a facile method. The water contact angle and sliding angle of the porous superhydrophobic magnesium oxide coating were 155±1.9º and 1.5º, respectively. The anti-icing property of the porous superhydrophobic magnesium oxide coating with low sliding angle was investigated in a climatic chamber with a working temperature of −6 °C. The results showed that the porous superhydrophobic magnesium oxide coating with low sliding angle can largely prevent ice formation on the surface, showing excellent anti-icing property. The porous superhydrophobic magnesium oxide coating with good anti-icing property will be perfectly desirable for outdoor equipments to reduce ice formation on their surfaces in cold seasons. This work will provide a new way to fabricate anti-icing coating and thus find applications in a variety of fields.
