Abstract:
1. A method of producing a carbon nanotube or carbon nanofiber comprising: performing centrifugal melt spinning of core-shell particles to obtain a fiber by pressing the core-shell particles against a plate heater using centrifugal force, wherein the core-shell particles are formed from a carbon precursor polymer and a thermally decomposable polymer that disappears as a result of heat treatment, the plate heater has a number of pores that penetrate therethrough in a thickness direction of the plate heater, and the heater is heated to a temperature at which phase separation of the core-shell particles is not caused; making the fiber infusible; and carbonizing the fiber after making it infusible to produce the carbon nanotube or carbon nanofiber.
