Abstract:
A bobbin includes a stratiform composite structure. The stratiform composite structure includes an amorphous carbon structure and a carbon nanotube film structure composited with the amorphous carbon structure. The amorphous carbon structure and the carbon nanotube film structure are combined by van der Waals attractive force and covalent bonds therebetween.
