Carbon nanotubes were synthesized from acetylene and hydrogen gas mixture directly on stainless steel plates by sequential combination of rf PECVD and thermal CVD. PECVD was used for nucleation and initial growth of carbon nanotubes while thermal CVD was utilized for further growth of them. In this way decoupling of nucleation and growth of carbon nanotubes was realized, and growth of carbon nanotubes...
Polyacrylonitrile(PAN)-based carbon fibers were tested as anodes for lithium ion rechargeable batteries. PAN-based fibers were first stabilized under tension in air at about 200 o C (stabilization tension) and then carbonized in different gas environments (carbonization atmospheres) at heat treatment temperatures (HTT) between 700 and 1500 o C. The carbon fiber electrodes were prepared...
