摘要	Carbon nanotubes with uniform density were synthesized on carbon fiber substrate by the floating catalyst method. The morphology and microstructure were characterized by scanning electron microscopy and Raman spectroscopy. The results of field emission showed that the emission current density of carbon nanotubes/carbon fibers was 10 mu A/cm(2) and 1 mA/cm(2) at the field of 1.25 and 2.25 V/mu m, respectively, and the emission current density could be 10 and 81.2 mA/cm(2) with the field of 4.5 and 7 V/mu m, respectively. Using uniform and sparse density distribution of carbon nanotubes on carbon fiber substrate, the tip predominance of carbon nanotubes can be exerted, and simultaneously the effect of screening between adjacent carbon nanotubes on field emission performance can also be effectively decreased. Therefore, the carbon nanotubes/carbon fibers composite should be a good candidate for a cold cathode material. (C) 2008 Elsevier B.V. All rights reserved.
