| 摘 要： | 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.
