Magnetic properties of multi-walled carbon nanotube-epoxy composites
Epoxy matrix composites have been prepared using as filler different weight fractions (0.03-1 wt%) of CVD grown multi-walled carbon nanotubes (MWCNTs) containing trapped iron nanoparticles. Magnetic characterization performed at room temperature with magnetic field between -19 and 19 kG shows that t...
