Inhibition Microbial Adherence of Superhydrophobic Surface on Aluminum in Seawater

A superhydrophobic film with an anti-corrosive propertyhas been fabricated on the anodized aluminium foil by myristic acid (CH3(CH2)12COOH, mya) chemically adsorbed. The surface structure and composition were then characterized by means of scanning electron microscopy (SEM) The static contact angle (CA) for seawater is measured to be larger than 150°. The fluoroscope and scanning electron microscopy (SEM) show the samples with the superhydrophobic film which is immersed into nature seawater for 24h significantly decrease adhesion of microorganisms. The appearance of the microorganisms is characterized by transmission electron microscopy (TEM). The study suggests the superhydrophobic film dose not only decrease the corrosion currents densities (icorr), but also microbially influencing corrosion acceleration inhibition (MICI) due to preventing colonization of microorganisms. A hypothesis is indicated that aluminums whit the superhydrophobic film could be used as a kind of excellent marine materials.
