synthesis of cu-cnt nanocomposite powder by ball milling

In this paper, to improve the poor wettability between the Carbon nanotubes (CNTs) and metal matrix, the mechanical alloying (MA) technique by the ball milling method was employed. Also, the CNTs were pre-coated to improve the agglomeration of the CNTs with copper powder. The main aim of this work i

Nov 06, 2017 · The effect of high-energy ball milling on two carbon allotropes, graphite and multiwall carbon nanotubes (MWCNT) in the presence of urea has been studied. Samples were investigated using Raman spectroscopy, x-ray diffraction, scanning electron microscope (SEM) and x-ray photoelectron spectroscopy (XPS). Nitrogen-doped graphene has been successfully synthesized via a simple
