Abstract: A hydrophobic coating was prepared via a simple NaCl-dissolution-assisted etching silicon template method. Epoxy resins with excellent properties were selected as the matrix. The effect of sodium chloride concentration and spraying times on the microstructure and wetting properties of the coatings were studied. The results showed that a multi-stepped rough structure was formed gradually with the increase of salt concentration and the spray times. After using saturated salt solution spraying 30 times, the water contact angle (WCA) of the surface increased from 80.2° to 130.0°, indicating its good hydrophobicity. Besides, the epoxy coating showed superior abrasion resistance and chemical stability for strong acid and alkali solutions. Even after 50 times of abrasion test, the hydrophobicity of the surface showed ignorable variations. Furthermore, the morphology of the prepared porous silicone template retained well after 20 cycles of pouring-demoulding, indicating its excellent reusable performance.
