Abstract: Based on the cooperation of the fluorated polyurethane and nano silicon oxide,super hydrop hobic coating was successfully fabricated on the surface of aluminium alloy. The super hydrop hobic coating was characterized and investigated by FT-IR、SEM and electro chemical measurement. The FT-IR result showed that silane coupling reagent (A1100) was grafted on the surface of the nano-disilicon oxide. Scanning electronic microscopy(SEM) and optical contact anglemeter(θ)indicated that rough structure was present on the surface of the coating, and the contact angle could reach up to156°with sliding angle smaller than 5°. The results of electro chemical measurements (EIS and polarization curve) showed that anti-corrosion property of aluminium alloy was greatly improved.
KeyWords: Super hydrophobic; Silane coupling reagent; Electro chemical measurement; Anti-corrosion property
