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

α-Fe₂O₃/epoxy resin composite superhydrophobic coating was prepared with α-Fe₂O₃ nanoparticles 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 E_corr of the composite coating is positive and the J_corr is 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.
