✦ Synopsis


Carbon nanotubes are synthesized directly on stainless steel (SS) 304 particles (ø70 lm) by chemical vapor deposition (CVD) in a fluidized bed system (FBCVD) without the addition of an external catalyst. The direct growth method was originally developed for a fixed thermal CVD furnace, it is shown here it can be extended to FBCVD in a demonstration of the ease of scale up of the direct growth method. The growth method is compliant with SS particles substrate microstructures in the form of dendrites. It is also shown the SS particles can be
