Robust α-Fe2O3/Epoxy Resin Superhydrophobic Coatings for Anti-icing Property

α-Fe2O3/epoxy resin composite superhydrophobic coating was prepared with α-Fe2O3nanoparticles and epoxy resin by spin coating method.The coating without epoxy resin has higher contact angle (CA) and lower ice adhesion strength (IAS),but the mechanical properties are poor.The α-Fe2O3/epoxy resin composite superhydrophobic coating exhibits good mechanical durability.In addition,compared with the bare aluminum substrate,the Ecorrof the composite coating is positive and the Jcorris lower.The inhibition efficiency of the composite coating is as high as 99.98% in 3.5 wt% NaCl solution.The difference in the microstructure caused by the two preparation methods leads to the changes in mechanical properties and corrosion resistance of composite superhydrophobic coating.
