Attachment of magnetic nanoparticles on carbon nanotubes using oleate as an interlinker molecule

Novel Fe 3O 4/carbon nanotubes (CNTs) nanocomposites were prepared by a polyol-medium solvothermal method using oleate as an interlinker molecule and characterized via X-ray diffractometry, X-ray photoelectron spectroscopy, transmission electron microscopy and vibration sample magnetometry. Results indicated that the Fe 3O 4 nanoparticles were successfully attached on the surface of CNTs and the nanocomposites were proved to be superparamagnetic with saturation magnetization of 50.0 emu g −1. A proposed formation mechanism of the magnetic nanocomposites was presented.
