| Abstract | Abstract. Copper film with rough structure is prepared on metal surface via electro-deposition. After modification of tetradecanoic acid, copper film presents super-hydrophobic property with water contact angle of 151.1 ± 3°, which could be attributed to the rough structure by trapping air. The adhesion test shows that the modified copper surface has low apparent water adhesion to the suspending droplet. Electrochemical measurement proves that super-hydrophobic film can inhibit corrosion of copper effectively. The method proposed in this paper is time-saving and facile to operate, and it offers a promising technique to prepare metallic surface with super-hydrophobic property. Intorduction Super-hydrophobicity plays an important role in many technological application including biotechnology, waterproof and self-cleaning coatings, medical devices, and so on. Especially, artificial super-hydrophobic surfaces have attracted extensive interests for their potential application in anticorrosion [1-6]. Generally, it is believed that the high surface roughness and low surface energy are the two important requirements for the fabrication of super-hydrophobic surface [7,8]. Based on this point, many methods have been proposed to prepare super- hydrophobic surface until now, including CVD, and so on[9,10]. However, there are many drawbacks for these methods, such as complicated fabrication process, expensive instrument. In this paper, electro-deposition method has been proposed to fabricate super-hydrophobic film on copper surface. The relativity of wettability on morphology is discussed based on SEM result. Furthermore, the inhibition effect of super-hydrophobic film to underlying copper is investigated with electrochemical measurement. |
