文摘The nanocarbonaceous material with helical structure is considered to be promising as nanocoils. Both left and right handed helical structures normally coexist and are disordered. So far, there has been no report about double or multi directional helical structures on an individual nanomaterial. In this paper, Multi directional helical structures were observed in an individual carbon nanofiber during the pyrolysis of acetylene at a mixture of C2H2∶ H2=2∶ 1. It is possible to control and prepare multi directional helical nanomaterial, and it can be used into new application area.
