摘要: In this paper we report the observation of enhanced field emission properties from thiolated multi-wall carbon nanotubes ( MWCNTs) produced by a simple and effective two- step chemical surface modification technique. This technique implements carboxylation and thiolation on the MWCNTs synthesized by microwave plasma chemical vapor deposition ( MPCVD) on the flexible carbon cloth substrate. The resulting thiolated MWCNTs were found to have a very low threshold field value of 1.25 V mu m(-1) and a rather high field enhancement factor of 1.93 x 10(4), which are crucial for applications in versatile vacuum microelectronics.
