Abstract
Thin films made of carbon nanotubes are called buckypaper (BP), which is expected to be applied to electronic devices. Usually, BP is made by the chemical vapor deposition method. In this study, we used the vacuum filtration method to make low-cost BP. To justify the outstanding electronic performance of the fabricated BP, it was utilized to make the air-cathode of the aluminum-air battery. Since the BP is lighter and has a larger specific surface area than the carbon sheet, the aluminum-air battery can be miniaturized while increasing its performance. Furthermore, UV-ozone treatment was also applied to further improve the performance of the BP because it is able to clean and improve the surface conditions.
