ナノスケールで均一な炭素被覆を施したアルミニウム陽極酸化皮膜の特性とその応用

抄録

  Uniform carbon coating on nanochannels of an anodic aluminum oxide film drastically changes its optical property and, as a result, the resulting carbon-coated film exhibits brilliant colors. The carbon deposited on the inner walls of the nanochannels plays a major role in this phenomenon. In addition, the coating makes the channel walls electro-conductive, hydrophobic and much more chemically stable. These characteristics are never found in the original film. Owing to such peculiar properties, the coated film is more attractive as a template for the production of nanomaterials, because the electro-conductivity enables the electro-deposition of metal on the inner walls of the nanochannels and the hydrothermal synthesis inside the nanochannels is also possible due to the chemical inertness.
