摘要

Nano-thin TiO_2 film on etched aluminum foil was prepared by the Sol-gel dip-coating method and annealing post-treatment at different temperatures;;then, Al_2O_3-TiO_2 composite oxide film on etched aluminum foil was fabricated by anodization in 13 wt% ammonium adipate solution. Nanostructures of TiO_2 film were characterized by means of X-ray Diffraction (XRD), Raman Spectroscopy (RS), and Atomic Force Microscope (AFM). TiO_2 nanostructured films are composed of anatase nanopartilces in size of 5-12 nm as annealed at 400 °C and 500 °C, and anatase-rutile complex nanopartilces in 5-15 nm at 600 °G. Compared with pure anodic aluminum oxide film, TiO_2 nanostructures effectively improved specific capacitance of the Al_2O_3-TiO_2 composite oxide film on etched aluminum foil, with an increment ratio of about 8.6%, 24.6%, and 33.3%, caused by anatase and ratile content increasing with annealing temperature from 400 °C, 500 °C to 600 °C, respectively. The specific capacitance of dip-coated etched aluminum foil annealed at 500 °C reached to a maximum after two dip-coating times with 28.3% enhancement.
