Abstract
Linear polyethyleneimine (PEI) was used as a non-covalent functionalizing agent to modify multi-walled carbon nanotubes (MWCNTs). Fe 3O 4 nanoparticles were then formed along the sidewalls of the as-modified MWCNTs through a simple solvothermal method. X-ray diffraction, Fourier transform infrared spectrometry, transmission electron microscopy, and vibrating sample magnetometry were used to characterize the MWCNT/Fe 3O 4 nanocomposites. Results indicated that Fe 3O 4 nanoparticles with diameters ranging from 50 to 200 nm were attached to the surface of the MWCNTs by electrostatic interaction. PEI was found to improve the electrical conductivity of the MWCNT/Fe 3O 4 nanocomposites. The magnetic saturation value of these magnetic nanocomposites was 61.8 emu g −1. These magnetic MWCNT/Fe 3O 4 nanocomposites are expected to have wide applications in bionanoscience and technology.
