Abstract

Inspired by microstructure characteristics of surfaces of typical plant leaves such as petal of red rose, the biomimetic super-hydrophobic surface of aluminum alloy has been successfully fabricated by laser processing and surface modification by DTS (CH₃(CH₂)₁₁Si(OCH₃)₃). The morphological features, chemical composition, and super-hydrophobicity of resultant surfaces were characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, and water contact angle measurements. The super-hydrophobic surface exhibited a microstructure consisting of myriad micro-scale crater-like pits. It is found that the super-hydrophobicity is synchronously governed by both the surface chemical composition and geometrical microstructure structures. The highest water contact angle of resultant surface reaches as high as 161.0°. Moreover, corrosion resistance property of these prepared films against NaCl solution is elucidated using electrochemical measurements; it is found that the corrosion resistance of aluminum alloy is also considerably improved.
