Abstract

The effects of grinding for different time in a vibrating mill with the mixture of Fe powder and multi-walled carbon nanotubes (MWNTs) were studied. The morphology and structure of as-ground MWNTs were carried out by X-ray diffraction (XRD) and High-resolution transmission electronic microscopy (HRTEM). The results showed that some closed ends of MWNTs were broken while ground for 8 hours, and the rate of broken ends increased with grinding time. The Field emission measurements demonstrated that the turn-on field of the sample decreased from 4.0 to 2.6V/μm after grinding.
