Research on Inhibition Marine Microbial Adherence of a Novel Nano-TiO₂ Coating on Aluminum

Abstract:

A novel nano-TiO₂ coating is prepared by vacuum dip-coating TiO₂ sol–gel onto the anodized aluminum surface. The particles of TiO₂ anatase is ﬁlled into the Al₂O₃ nano-pores formed by anodization. The structure and composition of the coatings are characterized by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD). The preponderant bacterium is identified as Pseudomonas lindanilytica strain IPL-1 through analysis of the sequences of S16 nRNA gene segment. In addition, the electrochemical results show that the TiO₂ coatings significantly reduce the corrosion rate of Al substrates. The UV reflection spectroscopy is used to determine and analyze that the nano-TiO₂ coatings could improve the light photo catalytic activity which decreases microbial influencing corrosion acceleration inhibition (MICI).
