【摘要】 将金属铝通过阳极氧化的处理构造了特殊表面结构,再浸泡于十四烷酸(CH₃（CH₂）₁₂COOH)中进行自组装,最终在铝表面构建了稳定的超疏水膜。通过扫描电镜（SEM）,接触角测量仪表征超疏水表面的形成机制与表面结构特征。通过静态挂片法获得金属铝在青岛天然海水中浸泡3天后表面的优势菌种,通过扫描电镜（SEM）、透射电镜（TEM）等方法表征了微生物对铝表面超疏水膜的影响,并利用电化学阻抗（EIS）方法研究了超疏水表面对铝在海洋微生物环境中的腐蚀行为的影响,证明了超疏水膜对铝在海洋中的微生物腐蚀具有明显的抑制作用。更多还原

【Abstract】 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 scanning electron microscopy（SEM） shows the samples with the superhydrophobic film which is immersed into nature seawater for 5d significantly decrease adhesion of microorganisms.The appearance of the microorganisms is characterized by transmission electron microscopy（TEM）.Moreover,the corrosion resistance of bare and modified samples in different mediums were investigated by electrochemical impedance spectroscopy（EIS）. Experimental results show that the superhydrophobic film dramatically improves resistance of microbially influenced corrosion.更多还原
