Abstract

We have synthesized carbon nanofibres (CNFs) in an ethylene–air flame on astainless steel substrate. Ten-minute specimens consisted of both nodules and carbonmicro- and nanofibres of various diameters up to . There are two kinds of primary fibres. The first are of nm thickness and show numerous kinks along their length. The second variety can havethicknesses of the order of and can grow to a length of . Nanofibre branching is also evident. The inclusion of periodic metal deposits in thenanofibres reveals a strategy by which it might be possible to encapsulate metal particles inorder to form connected CNF networks.
