抄録

Porous anodic alumina (PAA) with regular channel structure was chosen as a template, and highly ordered TiO<SUB>2</SUB> nanofibrils arrays were fabricated within the pores of PAA by a sol–gel process. A series of TiO<SUB>2</SUB> nanostructures obtained after the TiO<SUB>2</SUB>/Al<SUB>2</SUB>O<SUB>3</SUB> composite film was treated with the NaOH for different times. Contact angle measurements indicated that the surface structure strongly affected the wetting behavior of the TiO<SUB>2</SUB> nanofibrils. The wettability of the surface changed from hydrophilic to hydrophobic when the structure of aligned nanofibrils with end tips was obtained.
